Let me guess ... this is an OHCI host? It's probably kicking in the code that tries to meet the 50 second reset requirement for root hub port resets. An individual port reset is probably 10 msec, so every 10 msec it issues another. > get_device_descriptor - reset - set_address sequence. The observations > on both these pc's is invariable.

OHCI only has it because otherwise the driver failed some conformance tests a while back. - Dave ------------------------------------------------------------------------- Using Tomcat but need to do more?
