I use a little USB audio in/out adapter [1] for $9.99 > Also, attaching the USB controller pci to win7 will stop win 7 from > booting. It will say "no bootable device was found" when I run it. And if I get this error if there is any storage media connected on USB when I boot the Windows VM. Maybe try again and make sure nothing is connected when you boot. Also: for some strange reason I need to limit my VMs memory to 2048MB when attaching the USB controller. Otherwise it'll crash.

The way this is implemented in Qubes is using USBIP but instead of a network IP connection it uses the XEN qrexec mechanism: https://github.com/QubesOS/qubes-app-linux-usb-proxy So I tried to run USBIP in Windows and run an unchanged USPIP host in sys-usb a couple years back and that worked for simple devices / protocols (e.g. USB-to-serial interface but not more complex USB devices like RealICE debuggger). So I gave up on that and instead have dom0 scripts to easily switch the controller between sys-usb, app-dev and app-win. /Sven [1] TROND External USB Audio Adapter Sound Card with One 3.5mm Aux TRRS Jack for Integrated Audio Out & Microphone in https://www.amazon.com/gp/product/B07L56C28R/ -- public key: https://www.svensemmler.org/0x8F541FB6.asc fingerprint: D7CA F2DB 658D 89BC 08D6 A7AA DA6E 167B 8F54 1FB6 -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
