>Description:
VT83C572 UCHI controller does not work on NetBSD 1.5_ALPHA2.
It is probed and uhub0 is also attached normally,
but if any USB device is pluged to USB connector,
the kernel says:

 uhub0: device problem, disabling port1

and when the device is removed the kernel says:

 uhub0: port error, giving up port1

All USB devices work fine with Windows98 on the same machine.

>How-To-Repeat:
Boot kernel with VT83C572 UHCI and plug any USB devices.

>Fix:
Unknown.
