The first trace seems to be a full-speed USB 1.0 device, while the last one that Steve sent to me is a low-speed HID device. Windows XP asks for 18 bytes for the first Get-Device-Descriptor for low-speed USB 1.0 (and probably 1.1) devices. You are right about the port reset though. Laurent Pinchart
