Thanks a lot for the instruction. Will the suspend/resume support be =
added in the future release?=20

Without the suspend/resume support, is there anything can be done in the =
guest domain to help detect a USB device? Maybe patch the kernel?

Thanks

The uhci emulation has no suspend/resume support.  From your description
this is exactly the problem you are seeing.
