Description caa 2000-07-05 21:00:01 UTC

usb.ko output the following when loading.
uhci0: <Intel 82371AB/EB (PIIX4) USB controller> port 0xe000-0xe01f irq 9 at device 7.2 on pci0
usb0: <Intel 82371AB/EB (PIIX4) USB controller> on uhci0
usb0: USB revision 1.0
uhub0: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered
uhub0: port 1 power on failed, IOERROR
uhub0: port 2 power on failed, IOERROR

usbdevs -v lists devices, but trying to open /dev/ugen gives devices not configured.

How-To-Repeat: reboot and load usb.ko

The bogus 'IOERROR' message has been fixed. 

The fact that ugen gives you a 'not configured', might be because 
you have not configured ugen into the kernel. Could you send 
me the output of the following 2 programs fi the problem 
with ugen is still present? 

dmesg 
kldstat -v 

Thanks for submitting the bug report.
