How to fix the UVC camera DEVICE ID

Jskim

Hi Support Team,

[This is an inquiry regarding a UVC camera.]
We are using the voxl-mini as shown below.

hw platform: M0104
voxl-suite: 1.4.5
SKU: TF-M0104-6-V1-C6
video codec(voxl-streamer): h.264
Web camera: uvc(YUY2) format

[Inquiry]

We are using a web camera.
The Device ID changes when the camera is turned back on (see figure below).

Therefore, we execute the command "systemctl restart voxl-uvc-server" every time.
Please tell me how to fix the Device ID.???

Thank you.
Kim.

Hi Support team,

I would like to know how to resolve the issue regarding the DEVICE ID change.

Could you please provide a solution for the above?

e.g., Will creating a udev rule file resolve the issue?

Thank you.

@Jskim , you should check dmesg to see maybe there are some warnings. Perhaps the device is not de-initialized properly (how are you powering it off?) and next time the OS allocates a new Device ID.

Either way, using udev rule should help resolve the issue, however make sure there is no resource leak as a result of the device on/off. Also, if you keep turning the device on/off, does the device ID increment indefinitely?
