It might be a Windows driver problem triggered by qemu timing differences (try reinstalling the printer drivers?) You might also try enabling DEBUG in usb-linux.c and compare the output you get there with a usbmon capture on the host, and a usbsnoopy capture on the guest, to see if there are any discrepencies. Not sure what kind of thing you'd be looking for, though. -jim -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
