Disconnect every 15mn Virtualbox Win10 Host - Freeze VM guest every day

[Pascal66]

Dont know if it's related to the driver win10, virtual box usb driver, or kernel of the VM

Running on USB 3.0 (The PICe doesnt work with virtualbox)
Continuous error, starting from 'unable to get BOS descriptor...'

Tryied slow or fast version, usb 2.0 or 3.0 port
(Dont know if it work on usb C port)

I've stabilised things (65ms inference), using the maximum powermanagement of everything in win10 host.
Just the "unable to get BOS descriptor or descriptor too short" at initialisation
20mn->No more Transfert event error for now.

30mn-> Just 5 comp_code 1 followed by 1 comp_code_13 after 30mn, and restarted with get BOS descriptor, without disconnecting
That happen, when the inference time is going from mean 65 to mean 75 (thermal thing ?)
Just after that everything fo normal

@Pascal66 Are you able to run the device successfully on native/host OS installation instead of the VM ?

[Pascal66]

@manoj7410 I've no dev environment in the W10 host.

[Pascal66]

Some news, after tryied all energy saving combinations on w10 host, I put all to normal.
I do that because I suspect something else than energy saving causing my problems.
No more success, but that confirm that power saving on w10 host isnt the problem.

[Pascal66]

New version :
Same as before.
So it's a VM problem maybe
