Describe the bug Running python3 demo_script.py --app uvc with OAK-D-Lite creates /dev/video device(s) only for a few seconds, the camera then disconnects and reconnects again as a non-uvc device, the /dev/video devices disappear.

To Reproduce (interlaced with console and dmesg outputs)

Connect OAK-D-Lite

dmesg:

The two "sometimes" alternatives happen seemingly at random, I have not noticed any pattern.

The UVC app should work, i.e. provide a working UVC device(s).

**Additional context**
The OAK-D-Lite is connected via USB-C to USB-A cable, sadly only an USB 2 cable. I'm getting an USB 3.1 cable very soon.

Luxonis-Brandon commented 2 years ago

Thanks for the thorough details and sorry about the trouble here!

I just reproduced the problem using a USB2 cable on an M1 Max Macbook Pro with my OAK-D-Lite. And then using a USB3 cable it actually worked fine:

So this is something to do with using a USB2 cable and the device acting as a webcam (UVC).

So the USB3(.1) cable you are getting should resolve this. I will need @alex-luxonis insight on UVC over USB2. I tried with python3 depthai_demo.py -usbs usb2 -app uvc but this had no impact, which I think makes sense as I don't think the usbs flag would have any bearing on UVC, as it's a setting for the actual DepthAI communication, not UVC communication.

Thanks and sorry again about the trouble.

VanDavv commented 2 years ago

@Luxonis-Brandon I just enabled CLI arguments in apps and we can use -usbs usb2 - but it doesn't make UVC app work. Now, opened from PhotoBooth, I see the same artifacts I saw when testing on Jetson (and that's why this app is disabled on this platform). Gave it a try on Windows 10 now and didn't work with USB2 connection as well, so I disabled UVC app if it's detected (so only USB3 allowed) until we get this solved, PR here - https://github.com/luxonis/depthai/pull/618

CC @alex-luxonis on the screenshots below, I saw the same artifacts on Jetson, reproduceable using python3 depthai_demo.py --app uvc -usbs usb2 (but commenting out the SystemExit line)

zegkljan commented 2 years ago

I just want to quickly confirm that with a proper USB3 cable UVC works flawlessly. I don't think UVC not working over USB2 is necessarily a problem, it just should be advertised, or the UVC app should refuse to run with just USB2 (and explain why). But UVC over USB2 would certainly be nice.

VanDavv commented 2 years ago

Thanks @zegkljan for testing and happy it's resolved on your side. With #618 merged, the UVC app will exit gracefully with a message suggesting USB3 cable usage and informing that we're working on solving the issue, as you suggested - best what we can do until it's resolved

Luxonis-Brandon commented 2 years ago

Thanks, all! And agreed we should just properly make a warning that says USB2 is not supported via webcam mode as of yet.

arafattehsin commented 2 years ago

Hi folks! Since this is open and I am not super familiar with what is going on (or the background of it). I am trying to run it as a webcam. I can see that I am able tolaunch depthai_demo.py and when I click on this

It gives me this in console

But when I try to access the app through any Camera app (or even OBS), I get this

~~I am absolutely sure that my cable is USB C (with USB 3) and the port is also USB 3.~~

Luxonis-Brandon commented 2 years ago

Odd. So the system thinks it is connected to USB2 only here. To debug, when running the demo app gui could you do lsusb and share the output here?

alex-luxonis commented 2 years ago

Hi @arafattehsin, As it's a Windows machine, may be a little more complicated to check the USB speed in the system, but our demo should print it. Do you see UsbSpeed.HIGH (equivalent to USB2) as below when the demo runs in standard mode?

Using depthai module from:  C:\Users\user\AppData\Local\Programs\DepthAI\venv\lib\site-packages\depthai.cp39-win_amd64.pyd
Depthai version installed:  2.14.1.0.dev+27fa4519f289498e84768ab5229a1a45efb7e4df
Setting up demo...
Available devices:
[0] 18443010915E1DF500 [X_LINK_UNBOOTED]
USB Connection speed: UsbSpeed.HIGH
Enabling low-bandwidth mode due to low USB speed... (speed: UsbSpeed.HIGH)

If that's the case, what type-C cable are you using, are both ends type-C, or it's type-A to type-C? With the latter, there's a possibility the device could be enumerated in USB2 mode if type-A is plugged first (so it's powered) and then the type-C end is plugged into the device and it's done "slowly" (first the power pins inside the type-C making contact, then data pins). A power-cycle (cable reconnection) is needed to recover from this.

The console logs are fine for the first part, I'm observing the same on Windows, it doesn't advance to printing the status unless an UVC consumer (e.g. Camera app) is started.

alex-luxonis commented 2 years ago

Unrelated to the above, adding a general note for the differentiation between an USB2 and USB3 cable, as many type-C cables on the market are USB2-only. If the other end is type-A, the color usually should be blue, or it can be checked if a row of 5 extra pins exists deep inside the connector: (image source)

arafattehsin commented 2 years ago

@alex-luxonis and @Luxonis-Brandon - thank you so much for these details and very helpful responses.

I re-run again and saw this (I think I get your point here @alex-luxonis)

After noticing my cable, I think what I wrote is not correct and your explanation makes sense. The USB A connector is different than what you have posted here about USB 3.

Now, the question becomes, is it because of USB 3 cable that my OAK D Lite is not working as a webcam or is there anything else I have to do as well? Just curious. I am happy to get a new cable (with USB 3 for sure)

VanDavv commented 2 years ago

@arafattehsin replacing the cable with USB3 one should resolve this issue

alex-luxonis commented 2 years ago

We'll also fix the USB2 issue (hopefully within 1..2 weeks), but the performance with USB3 will be better for uncompressed streaming.

At the moment, the UVC configuration is 1920×1080 NV12 (1.5 bytes/pixel). (the camera is actually configured at THE_4_K resolution with 2x downscale - this gives sharper images than THE_1080_P with scaling/binning on-sensor)

The bandwidth required for 30fps is: 1920 * 1080 * 1.5 * 30 = around 94 MB/s. USB2 can't sustain this, so we'll probably lower the resolution to 720p with USB2. And further will look at enabling JPEG or H.264/H.265 (AVC/HEVC) encoding with UVC.

arafattehsin commented 2 years ago

@alex-luxonis - Please take your time but an option to choose the resolution (or launching it with the specific resolution option) will always be great, considering its 4K capabilities. 🙂

arafattehsin commented 2 years ago

@alex-luxonis @Luxonis-Brandon - folks! USB C (3.0) arrived and works great. Woohoo! I will open up an enhancement soon which I think would add some values to the Oak D Lite as a product offering.

Luxonis-Brandon commented 2 years ago

Awesome thanks for confirming! And sounds great!

Suisse00 commented 2 years ago

Hi guys, So I'm the cheap guy running on a computer with only USB2 (and thus a USB2 cable) on Windows 10 (x64). I don't know if I'm the only one but your workaround to close (and prevent) using USB2 doesn't quite work here.

There is even something strange when looking at the console. Calling dai.Device(pipeline, usb2Mode=False) (even with usb2mode=True):

~~- Always end up blocking forever (so your warning/SystemExit(1) is never called)~~

Log stop working. Sometimes, I have half of a line about temperature sensor opened before it stop, sometimes everything from temperature sensors (but still freezes), sometimes it ends with the timesync line, ...

~~This is just for your information.~~

Turn out, I was unlucky enough so part of my issue was my software wasn't detecting the UVC in the first place. I just figure out that your warning show up when you connect to the webcam (put a facepalm here)

brmarkus commented 2 years ago

Do you use an actively powered USB-hub? USB2 versus USB3 is also about how much power could be provided to the end device. Which OAK-device do you use? (there are OAK-devices allowing to add an external power-supply to)

Suisse00 commented 2 years ago

(If needed we may create a new issue specifically for me, especially for the log part).

OAK-D-Lite.

I tried two ways to power it (because It was also one of my concerns) using the "Y" splitter (dedicated power port). The data line is always on that cheap USB-2 computer.

One using a USB 2 Type-A powered hub (Amazon Basic (yeah I know...)) using the dedicated "fast charge port" (1.5A) powered from an external power source. However, since OAK-D-Lite it is an USB-C I thought you may support USB PD only which lead me...

To test using a USB-C 3.1 on a always on port from a laptop. (I also tried on the Type-A USB 3.1 port)

In every case I didn't hear any USB disconnect from the host which could lead me to think the power going to the OAK-D-Lite was way too low. However, I know the OAK-D-Lite may get enough power to not disconnect from host but not enough to work properly :/ (If only wireshark USB could work on that damn Windows host!)

Warning: Keep in mind, when I use a Type-A USB port I'm using a Type-A to Type-C wire which is likely to not be USB 3 compliant!

hg111 commented 1 year ago

Hey guys,

We recently (Dec. 2022) purchased an OAK-D PRO W and we are having the same issue of not being able to run the camera as a webcam on Linux aarch 64 Ubuntu 20.04.

The error when running v4l2-ctl --list-devices : Cannot open device /dev/video0, exiting.

and ls -lrt /dev/video returns: ls: cannot access '/dev/video*': No such file or directory

lsusb does not list the OAK either

The only port on the camera is a USB-C and the cable we use is fairly new USB-C cable which we plug into USB-3 Type-A (Blue) adaptor on the PC side. We tested and this cable works perfectly with a Webcam. is there something else we should try? a 'patch' or some other solution or workaround?

Note: perhaps related is the comment here: https://unix.stackexchange.com/questions/678358/logitech-c920e-v4l2-ctl-list-devices-cannot-open-device-dev-video0-exiti

"Since the driver does not seem to detect your camera, it's possible the camera presents itself to the USB bus in some non-standard way that will need to be handled specially by the uvcvideo driver maintainers."

and in the faq: https://www.ideasonboard.org/uvc/faq/#faq1

if our device is a uvc device. running the command: lsusb -d -v | grep "14 Video"

should see a number of lines like this:

bFunctionClass 14 Video bInterfaceClass 14 Video ...

so is it missing the correct uvc drive ?

Erol444 commented 1 year ago

Hi @hg111 , Have ran the UVC pipeline? Docs here.

hg111 commented 1 year ago

yes, running python3 depthai_demo.py --app uvc we get:

"This app is temporarily disabled on AARCH64 systems due to an issue with stream preview. We are working on resolving this issue"

$ python3 ~/Luxonis/depthai/depthai_demo.py --app uvc

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.1.0 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

@Jai-GAY you'd want to use numpy 1.x. I'd suggest to use UVC example directly: https://docs.luxonis.com/software/depthai/examples/uvc_rgb/

tried this, and it seems okay after I ran this requirement.
