Assigning USB to VM fails

[Max Andersen]

I have trouble attaching my USB RJ45 adapter. I get the following error :

[Max@dom0 ~]$ qvm-usb -a lokal-belkin sys-usb:3-2
ERROR: Device attach failed: No device info received, connection failed,
check backend side for details
[Max@dom0 ~]$

It is properly attached to sys-usb:

[Max@dom0 ~]$ qvm-usb
sys-usb:2-1.8    5986:0535 Generic_Lenovo_EasyCamera_200901010001
sys-usb:3-2    0b95:7720 ASIX_Elec._Corp._AX88x72A_10FD4D
sys-usb:2-1.1    046d:c52f Logitech_USB_Receiver
sys-usb:2-1.7    04f3:016f ELAN_Touchscreen
sys-usb:2-1.6    2047:0855 Invensense_Lenovo_Yoga_31F3806F24001100
sys-usb:2-1.4    8087:07dc 8087_07dc
[Max@dom0 ~]$

I documented the behaviour earlier for future reference here:
https://www.militant.dk/2018/02/20/add-usb-network-adapter-to-a-specific-qube-to-configure-router-in-qubes-3-2/

It seems it has worked and now it doesn't. Users might have had similar
issues before

Any ideas?

Sincerely

If you're using a new template for sys-usb or lokal-belkin, have you
installed the qubes usb proxy in both and qubes input proxy sender in
sys-usb? Going off memory so can't remember the package names exactly.

I remembered changing template to debian as sys-usb, since fedora can't handle large USB drives with exFat, so I swithced back to fedora-26. That didn't help though.

I have qubes-input-proxy-sender and qubes-usb-proxy in the template.

And qubes-usb-proxy installed in the template used for lokal-belkin? If
so, I'm not sure what else it could be...

Yes it is. I don't know either. It seems that RedHat should just get exFat fs support and everything would have been fine :)

I guess I need to have 1 sys-usb for offloading images from my camera and 1 sys-usb for local networking via usb. Weird, but I will maybe try from scratch with sys-usb on debian.
