Issue Description

Hi all, I bought an L515 camera from the Intel store a week ago. It doesn't work. The RealSense Viewer always reports Found 0 RealSense devices. At the OS level, the USB 3 device always returns an error. After that, it will only be recognized as a USB 2 device. Output of dmesg:

I've already tried the following:

Is there any way I can fix the error? Can someone help me please?

The same error occurs on Linux Mint, based on Ubuntu 18.04, with Kernel 5.4.0.

Is there any way to update the firmware to v1.5.1.3, because it supports USB2?

Any help would be greatly appreciated.

ofl1 commented 3 years ago

Error -71 always occurs when the kernel communicates with the USB3 device. -71 means protocol error. I examined it more closely with Wireshark. Here is a screenshot of it.

Screenshot_Wireshark_USB_RealSense

The host requests configurations. The device responds with some valid configuration descriptors. Some valid interface descriptors follow and finally a malformed packet. The URB announced a data block with 512 bytes. The last three bytes of this data block are the beginning of an incomplete video streaming interface descriptor. The host makes two more attempts, resets the port, and tries three more times. Then it blocks the USB3 device completely and continues via USB2. USB2 is apparently not supported by the firmware that is on the device.

Could this be a bug in the firmware? Can you find a workaround for this? Is it possible to update the firmware bypassing the kernel?

ofl1 commented 3 years ago

I made a small change in librealsense so that the L515 is recognized even though it is not entirely okay.

In Wireshark you can see that the device replies to the first sent 1024-byte block of the firmware with protocol error (-71).

Is the device faulty? Or can it be made to work somehow?

RealSenseSupport commented 3 years ago

Hi @ofl1

Sorry to hear the device isn't able to be recognized as a USB3 device. I know you're working and operating under Linux, just confirming you're having the same problem under Windows as well?

If possible just download the RealSense Viewer executable directly (https://github.com/IntelRealSense/librealsense/releases/download/v2.40.0/Intel.RealSense.Viewer.exe) under Windows and see if the FW update process within the Viewer itself cannot update the FW.

If the FW update process does not work, you may need to RMA the device and request a replacement.

ofl1 commented 3 years ago

Thank you for your response. Under Windows, the behavior is unchanged (see above). The RealSense Viewer reports:

 02/12 09:04:31,350 DEBUG [7604] (win-helpers.cpp:87) res=pSensorManager->GetSensorsByCategory(SENSOR_CATEGORY_ALL, &pSensorCollection) returned: HResult 0x80070490: "Element nicht gefunden."
 02/12 09:04:31,350 INFO [7604] (context.cpp:381) Found 0 RealSense devices (mask 255)

The device manager first reports "The device is working properly", and after a few minutes "This hardware device is not currently connected to the computer. (Code 45)", although the device is still connected.

I had already requested a replacement. Now the return label has finally arrived. That's a strange error, isn't it?

Hi @RealSenseSupport , could you help me to solve this problem, I expect feedback from you, thank you!

any update? after multiple attempts, cannot even detect the device @RealSenseSupport

What we have been noticing is that some systems USB3 controllers aren't able to for some reason connect the L515 camera as USB3 device. So as we've outlined in some of our whitepapers and in certain configurations that a USB3 powered hub works. We've been suggesting to try for these issues where USB controller compatibility issues with L515 camera to use something like this hub: https://www.amazon.com/dp/B00DQFGH80/ref=asc_df_B00DQFGH805315309/?tag=hyprod-20&creative=394997&creativeASIN=B00DQFGH80&linkCode=df0&hvadid=167151358503&hvpos=1o1&hvnetw=g&hvrand=9308811005364068537&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9032905&hvtargid=pla-281221827342

I'm having this same problem with the D415. I bought the hub but I am still seeing that it is recognized as USB2 instead of USB3.

RealSenseSupport commented 3 years ago

@dqii

Has moving to another system with a different USB controller or using a powered USB3 hub work for you on the D415?

dqii commented 3 years ago

@RealSenseSupport I'm only able to get it to work if I attach the USB3 cable that came with the camera to the camera. I'm able to add a hub and a USB-A->USB-C converter in between. I tried attaching multiple different USB3 cables to the camera, but none of them worked. The cable that came with the camera is too short for me, so ideally there would be a way to use a different USB3 cable.

For what it's worth, I noticed the USB3 cable that came with the camera has a cord labelled as 3.0, but that it's recognized by the software as 3.1. All of the USB3 cables I have tried have been recognized as USB2

RealSenseSupport commented 3 years ago

@dqii

Definitely need to make sure that the cable is certified USB3 cable.

ofl1 commented 3 years ago

Today a quick update from me. All advice regarding USB cables and self-powered hubs has not worked for me. I sent the device to RealSense for a firmware update so that I can at least use it in USB2 mode.

In the meantime, I bought a small PCIe card with a USB3 port and plugged it into an old PC. At this port the L515 then worked in USB3 mode!

The problem was the USB host controller. Both PCs that I tried before have ASM1042's. Two are on the mainboard of an eight-year-old PC, another one in an ExpressCard that I bought new. Controller driver and firmware updates did not help or were not possible. The PCIe card has a different USB controller and the L515 works with it.

In order to be able to use the ASM1042, I patched the kernel. I adapted the module xhci_hcd. With this change, the operating system correctly recognizes the L515 as a USB3 device. The tools realsense-viewer, rs-enumerate-devices and rs-hello-realsense then work partially, but with many warnings and errors.

Perhaps this information will help someone who also has this controller.

ofl1 commented 3 years ago

Here's a recap of how I got the camera working.

Desktop PC: PCIe card with Renesas uPD720202, tested under Linux and Windows Laptop: ExpressCard with Fresco Logic FL1100, and self-powered hub (atolla or amazon basics), tested under Linux

The ASM1042 is not suitable. At best, the L515 runs in USB2 mode on this controller. But the resolution is then low: only 320x240 Depth and 640x480 RGB. In USB3 mode you get a lot of errors and crashes. I don't understand why this ancient controller is still being sold. RealSense support could alert users who have this controller to the problem.

Thanks @ofl1 - appreciate the detailed testing on the controllers. We will keep this information available to alert others regarding this controller.
