4 years ago I'm having similar issues with my Lenovo T490s. I also have 4 cameras and /dev/video2 is the IR camera. The v4l2-ctl -d /dev/video2 --all output is identical except mine has a driver version of 5.3.7 and a bus info of usb-0000:00:14.0-8.
Could you check your output of lsusb to see if we have the same chip?

4 years ago Yep is the same
# lsusb
Bus 003 Device 002: ID 04f2:b67c Chicony Electronics Co., Ltd Integrated CameraI found this in the Windows 10 SDK documentation: https://docs.microsoft.com/en-us/windows-hardware/drivers/stream/uvc-extensions-1-5#22211-ir-torch-control
Judging from the output of lsusb -d 04f2:b67c -v the device seems to have multiple extended control units, including the microsoft extended control unit described in the article and also a realtek extended controls unit:

iExtension 10 Realtek Extended Controls UnitI also stumbled over this: https://linuxtv.org/downloads/v4l-dvb-apis/v4l-drivers/uvcvideo.html
I have little experience with USB drivers but haven't done anything with uvc. The command v4l2-ctl -l -d /dev/video2 doesn't return anything.
Maybe this is helpful to someone? I can also provide usbpcaps of a Windows 10 application (Mirametrix Glance) turning on the camera and the IR-LED.

4 years ago After adding some debug prints to the uvcvideo kernel driver, I managed to figure out that the extension unit supports MSXU_CONTROL_EXPOSURE, MSXU_CONTROL_FACE_AUTHENTICATION, and MSXU_CONTROL_METADATA. The second one sounded promising.
The code below sends a UVCIOC_CTRL_QUERY ioctl to /dev/video2, setting the "Authentication Alternative Frame Illumination" mode on the device. This will make the IR LED alternate between on and off for each video frame (when video is streamed, e.g., using VLC or howdy test). Unfortunately direct IR Torch control (MSXU_CONTROL_IR_TORCH) doesn't seem to be implemented/supported.

0b010 // bmControlFlags
// Bit0: Authentication Disabled
// Bit1: Authentication Alternative Frame Illumination
// Bit2: Authentication Background Subtraction
// Bit3-55: Reserved, set to zero
};
struct uvc_xu_control_query set_query = {
.unit = 10, // bUnitID
.selector = 0x06, // MSXU_CONTROL_FACE_AUTHENTICATION
.query = UVC_SET_CUR,
.size = 9, // only one endpoint so 1+1+7
.data = (__u8*)&setbuffer,
};
int fd = open("/dev/video2", O_WRONLY);
int result = ioctl(fd, UVCIOC_CTRL_QUERY, &set_query);
if (result < 0) {
printf("Error code: %d, errno: %d, error: %s\n", result, errno, strerror(errno));
}
close(fd);
return 0;
}Nice findings. I don't have any experience on this low level c code so I can't help you develop but if you need someone to test I can surely do that on my device with some instructions on how to do it

4 years ago I think I found the right call. In the wireshark USB dump I found URB_CONTROL messages transmitting only 2 bytes of data:
bmRequestType: 0x21
bRequest: 1
wValue: 0x0e00
wIndex: 0x0e02
wLength: 2
Data: 0x0219The index tells us this corresponds to unit 0x0e (Realtek Extended Controls Unit, GUID 26b8105a-0713-4870-979d-da79444bb68e), interface number 2. The value tells us the selector 0x0e.
I don't know what the first byte of the data does. The second byte seems to control the brightness of the IR emitter. It's maxing out at 0x19 already. I've found another call with data = 0x0264.
The following C code would turn on the emitter:
__u8 setbuffer[256] = {0x02, 0x19};
struct uvc_xu_control_query set_query = {
.unit = 0x0e,
.selector = 0x0e,
.query = UVC_SET_CUR,
.size = 2,
.data = (__u8*)&setbuffer,
};
int fd = open("/dev/video2", O_WRONLY);
ioctl(fd, UVCIOC_CTRL_QUERY, &set_query);
close(fd);I've put a small tool written in C to toggle these values on https://github.com/PetePriority/chicony-ir-toggle. The repo also includes a python script that does the same. The IR emitter should turn on as soon as you start streaming video from the device. The emitter turns off for some reason as soon as the image turns too dark. Then it's necessary to reopen the device again.
@DavidM42 could you test if this works for you?

4 years ago @PetePriority Wow very nice. That worked for me to enable the IR emitter. I used the gcc command to build it. Still have to work out adding a new face model now

commented
4 years ago Try adjusting the dark_threshold value in your config file. I set mine to 80. I think there's a bug related to this value though. Could you try if #276 works for you?
DavidM42
commented
4 years ago Wow thanks! I monkey patched your PR into the installed files on my drive and set dark_threshold to 90 and now it works

4 years ago I'm in similar shoes with Lenovo Yoga X390 but in my case the device is: Bus 001 Device 005: ID 13d3:56ba IMC Networks
Assuming the only option is to "Wireshark" the communication with working Windows solution, could someone guide me to do it? Sorry for beginners question but actually never used it before.
Do you work with Wireshark on the Windows Host, or Linux host (here Ubuntu) and Windows Guest on VirtualBox and USB redirects? If the second one, let me know, please if you use Wireshark on the Host side or Guest one?
Thanks in advance,
P.

4 years ago @pczekalski Could you post the output of lsusb -d 13d3:56ba -v?
I used wireshark on the Windows Host. It should also be possible to use it on a linux host with usb redirects to a VM. I recommend having a look at some guides/tutorials/videos on how to do it.
A first step would be to find the correct usb monitoring device that the camera is attached to. Then apply some filters to remove packets from other devices on the same bus, e.g., mice and keyboards. Another useful filter is to exclude isochronous URBs (that's the video stream) using the filter !(usb.transfer_type == 0x00).

4 years ago "Could you post the output of lsusb -d 13d3:56ba -v?" Absolutely, this is where I actually started ;-). I believe the IR camera is the one in the second part as resolution seems to be the one (640x360).

4 years ago @pczekalski Judging from the output your device seems to offer the same extension units as our cameras. Have you tried the workaround proposed in https://github.com/boltgolt/howdy/issues/269#issuecomment-548105971?

4 years ago Interesting, i think integrating your code @PetePriority could help quite a few users that have been reporting very dark IR images without the blasters firing.

4 years ago @PetePriority patch did not work on the ThinkPad TP25 (25th anniversary edition), Ubuntu 18.04, which appears to also use the Chicony camera. Building/installing patch and running 'chicony-ir-toggle on' as described on its project page results in
Error code: -1, errno: 2, error: No such file or directory
Is the TP25 using a different variation of the camera or am I missing a dependency? Make/build process went off without errors, only encountered at runtime.
Without blasters firing, the attached screenshot is my result. In brighter light, you can make out a silhouette, but that's it.

4 years ago @dsneath Please review main.c file. There is hard coded path to IR camea /dev/video2. It works for ThinkPad X1 Gen2 and some other, but may be different for other laptops. Please update main.c accordingly with your correct IR video device.

4 years ago Maybe Im going crazy but when I use the scrip on linux it break the ability of windows hello to turn on the cameras, had to restore to a backup two times in a row after using the script. Maybe Ill just be happy with using this tool with lighting and solve the IR thing later

4 years ago @JoaoVictorDaijo You're not crazy, I experienced that on the first reboot into Windows after running the fix as well. Mine kicked in after another reboot, though -- didn't resort to a backup.

4 years ago Well I managed to fix my issue, I went back to the forums and remembered that I have the option to say if my IR camera was working or not, so I removed Howdy installed again and cycled until it found my IR device. Now looks like its working. I also had to edit Howdy's dark threshold to 92 for it to work fine. (This is why you don't do stuff half asleep)

4 years ago I was having the same issue and managed to get the IR blaster to turn on with @PetePriority 's solution, however I noticed something interesting. I'm running a Manjaro 19.0.1/Windows 10 dual boot on a Razer Blade 15 (Mid 2019), and I was originally able to set up howdy with no issues. The IR blaster blinked until it found my face and unlocked flawlessly. My issue didn't start until I booted into Windows.
I didn't have Windows Hello enabled at the time, however after messing with howdy I decided to set it up. Windows Hello worked great, and it seemed like I had no issues until booting back into Manjaro; the IR blaster stopped working all together. Like I said I managed to fix it, however I noticed that the IR blaster stopped blinking and just stayed on.
This isn't really an issue—I can change I'm curious as to why booting into Windows would break it. The IR blaster flashing made it easier for the IR camera to see your face without having to mess with the dark_threshold and get it working—howeverdark_threshold value. Maybe Windows messes with it somehow?
Again this is mostly food for thought, but I figured I'd share.
Edit: I tried to add my face to howdy after turning on the IR blaster, but even at an absurd dark_threshold value (120) my IR blaster isn't powerful enough to get my IR camera to see my face unless I'm half a foot away from the camera. I guess I didn't fix my problem.

3 years ago Hi, I also have a Lenovo s740, but mine came with an IMC Networks Integrated Camera. I tried to run the code made by @PetePriority to enable IR emitters but no success. I captured some USB packets on windows and I believe I found the right call, however, I could not make it work by modifying @PetePriority code.
Here is the output of lsusb -d 13d3:56ba -v
lsusb_imc.txt
Here are the captured packets on windows imc_caputre.tar.gz
The packet which I believe enables the IR emitters has the following payload

3 years ago Just to update. I was able to enable the IR emitters, however they do not blink. They just stay on most of the time. Does howdy use the TOF principle to create a depth image or the IR emitter is used only to illuminate the face?

3 years ago Added an issue as https://github.com/PetePriority/chicony-ir-toggle/issues/11 to confirm that my Razer Blade 15" Advanced 2019 is now usable with Howdy. No changes required. However, the IR lamp isn't as bright as under Windows and I need to be much closer for it to produce usable images. You can see that the lamp is only a relatively small red dot, compared to under Windows. I might try and do a packet capture and see if I can figure it out.

Hi Hnagzhi, I just used this code as-is from @PetePriority on /dev/video2. Then, just configure howdy to source video from /dev/video2 instead of /dev/video0. This way the IR emitter will turn on, but it won´t blink as windows hello.

Thank you for your answer! So when I run chicony-ir-toggle, it just says Error code: -1, errno: 2, error: No such file or directory... Meanwhile, I noticed that my device does not use exactly the same webcam model, but a slightly different one with the ID 13d3:56fb

3 years ago Do you have /dev/video0 up to /dev/video3? Use lsusb to find out which one is the IR camera … On Sat, Aug 15, 2020, 17:50 Hangzhi @.***> wrote: Just to update. I was able to enable the IR emitters, however they do not blink. They just stay on most of the time. Does howdy use the TOF principle to create a depth image or the IR emitter is used only to illuminate the face? How did you manage to turn them on? Hi Hnagzhi, I just used this https://github.com/PetePriority/chicony-ir-toggle code as-is from @PetePriority https://github.com/PetePriority on /dev/video2. Then, just configure howdy to source video from /dev/video2 instead of /dev/video0. This way the IR emitter will turn on, but it won´t blink as windows hello. Thank you for your answer! So when I run chicony-ir-toggle, it just says Error code: -1, errno: 2, error: No such file or directory... Meanwhile, I noticed that my device does not use exactly the same webcam model, but a slightly different one with the ID 13d3:56fb — You are receiving this because you commented.

Yes. I know that video2 is the IR cam.

3 years ago Great job @PetePriority ! Works even for b6be on Lenovo ThinkPad L14 AMD Ryzen 7, but it is needed to change unit to 0x0d and the second data byte to a higher value, i.e. 0x20, to make it shine bright like a diamond.
Without changing unit, I get Error code: -1, errno: 2, error: No such file or directory

When I run chicony-ir-toggle on my Yoga Slim 7 AMD Ryzen 7 laptop, I get the same error message.

3 years ago https://github.com/EmixamPP/linux-enable-ir-emitter I tried to write a tutorial to help everyone modify the PetePriority code to work with all infrared cameras (which are at least supported with the kernel driver). I hope this will help you.

I tried your method but couldn't get it to work.
My data from VM is below:
Setup Data
bmRequestType: 0x21
bRequest: 1
wValue: 0x1400
wIndex: 256 (0x0100)
wLength: 10
Data Fragment: 00000000cf02ff040100So I changed the c file:
const char* device = "/dev/video2"; //your camera path
if((fd = open(device, O_WRONLY)) < 0){
fprintf (stderr, "Unable to open a file descriptor for %s\n", device);
return EXIT_FAILURE;
}
//Data Fragment
__u8 data[10] = {0x00,0x00,0x00,0x00,0xcf,0x02,0xff,0x04,0x01,0x00};
//You can use my python data-seq-to-hex script for format the data fragment directly in the buffer format.
//You just have to pass the data fragment in parameter
//Don't forget to change the buffer size with the value of wLength
struct uvc_xu_control_query query = {
.unit = 1, //2 first bits of wIndex
.selector = 14, //2 first bits of wValue
.query = UVC_SET_CUR,
.size = 10, //wLength
.data = (__u8*)&data,
};When running the compiled code, I always got error:
Ioctl error code: -1, errno: 2
The device does not support the given control or the specified extension unit could not be found.I also tried swap unit and selector, but still got the same error.
Any suggestion?

3 years ago @bobzhu418 0x14 is in hex base. So you must write either 0x14 (hex) or 20 (decimal). I will update the tutorial to make it clearer.

3 years ago @EmixamPP Thanks for your quick reply. I changed it but still got the same error. Is my Data Fragment part correct?
//Data Fragment
__u8 data[10] = {0x00,0x00,0x00,0x00,0xcf,0x02,0xff,0x04,0x01,0x00};
//You can use my python data-seq-to-hex script for format the data fragment directly in the buffer format.
//You just have to pass the data fragment in parameter
//Don't forget to change the buffer size with the value of wLength
struct uvc_xu_control_query query = {
.unit = 0x01, //2 first bits of wIndex
.selector = 0x14, //2 first bits of wValue
.query = UVC_SET_CUR,
.size = 10, //wLength
.data = (__u8*)&data,
};@bobzhu418 Have you tried another packet on wireshark ? Personally if I just open the test on windows without launching it, if the filter is applied I only have two packet which is displayed and only one of the two is the good one.
However, the steps for your camera to find the packet that activates the transmitter may be sent at another time. For example, it may be sent at the beginning of the test, so you have to launch it. Or at the moment when Windows turns on. Because with my camera Windows turns off the transmitter every time it is no longer needed but maybe not with your camera.
I can therefore only advise you to test as many cases as possible where the transmitter could receive a packet asking it to turn on. I remain available if you need more details, either here or on the repo I created.

3 years ago @EmixamPP Thank you so much for your help. I've managed to find the right setting for my IR camera. Now Howdy works great on my Manjaro setup. It did take me some time, but it was a great learning experience for me.
For anyone who may have the same laptop, my settings are below:
//Data Fragment
__u8 data[9] = {0x01,0x03,0x02,0x00,0x00,0x00,0x00,0x00,0x00};
//You can use my python data-seq-to-hex script for format the data fragment directly in the buffer format.
//You just have to pass the data fragment in parameter
//Don't forget to change the buffer size with the value of wLength
struct uvc_xu_control_query query = {
.unit = 0x0e, //2 first bits of wIndex
.selector = 0x06, //2 first bits of wValue
.query = UVC_SET_CUR,
.size = 9, //wLength
.data = (__u8*)&data,
};

3 years ago I can confirm that the script by @EmixamPP works for me. (And thanks to @PetePriority for providing the initial attempts! Though they don't work on my machine.)
I'm on Lenovo Yoga 14s (2021), with camera 04f2:b6cb Chicony Electronics Co., Ltd Integrated Camera.
4 video devices are shown as /dev/videoX, where video0 is the normal color camera, video2 is the IR camera.
Maybe it can be modified to read configuration file, so as to provide it as a package (e.g. AUR for archlinux)?

3 years ago @renyuneyun, yes it could be really nice ! Just having a script that reads the config file and modifies the C file could help those who have difficulty with this kind of manipulation. I'll try to do that soon.
Regarding AUR, indeed it would be cool for those who don't go on GitHub. I've never done this kind of thing, I'll have to find out or simply have someone else do it.

3 years ago @EmixamPP I'm happy to help in packing it as an AUR package :) I can do the initial version and hand it to you (or maintain under my mybuilds repository if you are reluctant in updating it yourself XD). It's a simple process once you know it.

Thank you for this - your project combined with setting the dark threshold above about 95 got the IR emitter working very reliably on my Thinkpad T14 Gen 2 AMD.
I'm sorry but I have another one of these IR Emitters don't turn on issues and I couldn't resolve it with the solutions of previous issues. My Lenovo Yoga S740 has 4 cameras registred under
/dev/video(0-3):I read that setting different resolutions could help so I tested some resolutions but sadly no width/height I tried helped (including 640/360).
Below the debug output for video2 (IR webcam):
v4l2-ctl -d /dev/video2 --allDevice: Lenovo Yoga S740 Distro: Pop!OS 19.10 (Ubuntu 19.10) Howdy version: 2.5.1 .deb installer because apt repository did not work
