USB 1.0 supports 1.5Mbps (low-speed) and 12MBps (full-speed). Hosts and hubs must support both, functions (devices) can use either. USB 1.1 was a bug-fix release which solved some interoperability issues arising from ambiguities in the USB 1.0 standard. -- http://mail.python.org/mailman/listinfo/python-list
