ÂHow do you interact with it? Yes, in windows, it can be accessed by a proprietary program. I just tried using it in qemu-kvm-0.13.0 with the same program. But qemu-kvm can not start. When it probed usb device, it consumed %100 cpu(for ever) with the output usb_create: no bus specified, using "usb.0" for "usb-host" husb: open device 2.2 husb: config #1 need -1 husb: 1 interfaces claimed for configuration 1 husb: grabbed usb device 2.2 Thanks.
