Here's the best thing to do to find out what is really happening: Use the usbmon facility to see exactly what data bytes are being sent to the computer (instructions in Documentation/usb/usbmon.txt). This will tell us for certain whether those garbage bytes are left-over junk in RAM or the device is actually sending them. You don't even need to use the patch I sent for this test, although it won't hurt.
