This is pretty amazing development and I must congratulate the Qemu developers. The only problem is the USB speed. I get only about 10kbit/s max! This is measured by downloading a 1MByte scientific camera image. Is this the expected USB speed at the moment or is there anything I can do to improve speed? Thanks
