[Qemu-discuss] QEMU for Windows USB passthrough

[Anastasios Vacharakis]

Hello,

i try to make USB Passthrough in Windows work (my DVB-S USB Receiver).

Steps done:

- Replaced Driver with libusbK, libusb-win32, winusb (tool:
http://zadig.akeo.ie/)
- Found following commandline to work: -device usb-ehci,id=ehci -device
usb-host,bus=ehci.0,hostbus=xx,hostaddr=xx

System: QEMU 2.9.0 rc2 from https://qemu.weilnetz.de/w64/, Windows 10
Version 10.0.14393

Response from QEMU:

qemu-system-x86_64.exe: -device usb-host,bus=ehci.0,hostbus=1,hostaddr=11:
libusb_kernel_driver_active: -12 [NOT_SUPPORTED]
ehci warning: guest updated active QH

VM: Arch Linux

usb 1-1: device descriptor read/64, error -110
usb usb1-port1: unable to enumerate USB device

There is no other QEMU for Windows version, which supports "usb-host".

Help is really appreciated,
Anastasios
