I'm sorry, but it still doesn't work :)
Do you run QEMU as root to be able to pass USB devices or as a non-root user?
I use the following to run VM in QEMU:
qemu-system-x86_64 -m 4G -cpu host -smp 4 -M q35 -accel nvmm -usb
-device usb-host -drive file=vm.qcow2 -nic user,model=e1000 -rtc
base=localtime
And I get the this error:
qemu-system-x86_64: libusb_kernel_driver_active: -12 [NOT_SUPPORTED]
Whichever bus/port I try, it always ends up with this error? What did I miss?
