AUKEY LM1 / Issues with Linux

Support
#1

Hello,

I’m using Linux Mint 20.3 and have tested this camera with multiples Kernels ( 5.8.0-38, 5.8.0-33 , 5.8.0-29 , 5.4.0-59, 5.4.0-58) and I always get strange behavior:

I did not unplug device here, yet a disconnection is detected (sometimes, it’s more).
Finally, I get the Failed to query message many times until I unplug the camera.

Usually, no software is able to work with camera. If a software detects webcam, it will be working only first time. If I quit this software and come back, camera is KO.

Any idea?

Thanks!

Sorry, isn’t this supposed to be the official support?

#3

Hey,

Same issue. Also running Linux Mint.

#4

Nice to learn I’m not exactly alone with this crappy bug.
I tried to change USB ports, toggle USB legacy support, … no effect.

I’d be really positive that someone @AUKEY support us btw…

Hey,
I have a similar issue over here. I am using PC-LM1E on an Ubuntu 18.04 with a 5.4.0 kernel:

$ uname -r

Tested with another machine running Ubuntu 20.04 with 5.4.0 kernel:

Ubuntu 20.10

when i try to use the device the first time, then it fails already and i am unable to use it. is it a similar problem?

#8

The signature looks exactly like the issue on my side.

[10622.004314] uvcvideo: Failed to set UVC probe control : -71 (exp. 26).

errno -71 corresponds to -EPROTO (protocol error in the Linux USB subsystem).

#9

I don’t have those exact error codes, but something seems weird in UVC… and still not a single word from AUKEY?

#10

Hi @bdgraue @Fred @f3anor @catalysm
Please contact our service team at support@aukey.com.

#11

Hey,

I contacted support via the email provided. Got a response saying I cannot use warranty. I don’t want to use warranty, I want it to work on my PC. So if anyone finds a way to make it work on Linux, please share.

#12

Hello,

I’ve contacted support too; they requested an order ID and then a video showing issue… whereas camera is almost not recognized lol. Btw, I’ll update thread.

#13

Same here. They want to apply warranty for (likely) an driver related issue. We’ll see…

#14

Same problem here. Any help would be appreciated.

#15

Hey Kelly,
thanks for the response. Actually, I would prefer to get the device working with Linux instead of applying warranty. It seems that either there is a bug in the Linux UVC driver or that PC-LM1E has some UVC compliance issues. The device works fine on Windows 10.

If you can create a contact, I can support working on an uvcvideo quirk for Linux or at least support debugging.

@f3anor good news. Hope they take advantage of your proposal!

#17

I had my camera working these Days with Chrome Beta and a friendly hosted Jitsi. But i am unable to use it for example with discord. There i have the problem all the time, when i try to connect the camera. It shows up there, but i cant start it. The discord program then hangs till i unplug the cam.

If there is any need for debugging, i am willing to help. @f3anor

I received my new camera from AUKEY, but, as expected, issue was not related to hardware but to Linux driver, UVC or USB sub-system. Whenever I plug the new camera, I get following messages:

#19

@f3anor, would you want to support us on this?

#20

Hey Fred,
your error signature matches exactly what I have observed.

Tl;dr No update / progress

I played around with the uvcvideo quirk modes with no success. When I disable the USB sound card of the PC-LM1E by blacklisting the snd-usb-audio kernel module, sometimes I was able to get a working camera - but I needed to plug and unplug the device a couple of times after boot to get it “working”. And even than it was not stable.
