Hi,
I have used WSL2 to attach/detach a USB webcam device to/from Ubuntu distribution,
The first time the usb webcam has been attached, and after detached.
But the issue came the second time when I tried to attached as new the usb webcam to Ubuntu distribution
using the same commands i.e : usbipd wsl attach --busid
but this time the WSL has show this error message :

usbip: error: Attach Request for 2-2 failed - Device busy (exported)

usbipd: error: Failed to attach device with BUSID '2-2'.

I don't understand why the webcam is defined as "busy " and I don't know how to solve this issue,
because now I can't attach the usb webcam to Ubuntu distribution and I can't use it.

Thank you very much, if you could help me to solve this question
Best wishes
Daniele
