Hi, Does anyone successfully use USB drive in Windows7 guest? If I pass a USB drive to Windows7 guest, Device Manager may find this device but the USB mass storage driver can't be installed successfully. I have tried many times. Is the emulated USB controller is so old and Windows7 doesn't support it? I can't use PCI passthrough feature to pass the whole USB controller to VM, because the hypervisor also needs to use some USB ports. If I use Windows XP or Linux, the USB drive can work well.

Replace sdX with your USB device. ... -device usb-ehci,id=ehci \ -drive if=none,id=usbstick,file=/dev/sdX \ -device usb-storage,bus=ehci.0,drive=usbstick \ ... If would like to add the device while your VM is running, you may omit the last two lines and add this one instead: -monitor telnet:127.0.0.1:11111,server,nowait,nodelay Add the device using the two commands below: echo "drive_add 0 id=usbdrive,if=none,file=/dev/sdX"| /bin/nc -w1
