If so, take a look at logs in both VMs (`sudo > journalctl`) for more details. Mmm so should I have qubes-usb-proxy in dom0? It doesn't seem to be a package available to install... Do I need to have the USB controller in a usbVM to use passthrough?
In the journal of dom0, when an attempt fails, I find this entry: dom0 qubes.USB+1-4-work[14779]: /bin/sh: /etc/qubes-rpc/qubes.USB: No such file or directory which, as far as I can tell, is not meaningful - that file is created by qubesutils.py in usb_attach() if it does not exist, and then deleted afterwards. If I create it manually with the same contents it expects, the file is not deleted and this line does not appear, so I don't think this means much. > On my system it looks like phone simulate disconnect + connect each > time the driver is unbound from it (which is needed also during USB > passthrough...).

I will try anyway, but if you confirm to me that an usbVM is absolutely necessary for passthrough (i.e.: it does not work from dom0 because there's no qubes-usb-proxy) I'll first go buy a PCI-USB adapter. -- Alex -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
