[Xen-devel] usbpassthrough of xen-4.1.2

[Qian Hu <qianhu2011@xxxxxxxxx>]

Hi, everyone!

I am working on the USB passthrough of Xen-4.1.2. My host OS  is Fedora 14 and the guest OS is win7.

According to the wiki page(http://wiki.xen.org/wiki/Xen_USB_Passthrough), 

xen supports passthrough of usb device from dom0 to guests. I have tried the Xen HVM guest qemu-dm usb1.1 emulation,

by specifying "usb = 1" and "usbdevice = host:xxxx:yyyy". But, the mouse could work, the keyboard and usb storage failed.

If I change the guest OS to winXP, it is surprising that only the usb storage can be detected in the guest. 

I have also tried the PVUSB, it didn't work either.

I am confused and don't know how to resolve it.  Could anyone help me?

Great thanks!

huqian
