So, I'm trying to get USB functional on an old i386 machine that only
supports USB 1.0... It works, but when I try to plug in a hub I get

This was working w/ code from around a month ago, but I don't remeber
which rev it was, and I forgot to save the old kernel.. This is from:

Interesting parts of dmesg:

The ugen0.2 is plugged directly into the one of the ports, and works..
Let me know if there is anything more info I can provide.
Hi,
Possibly increase the timing variables under:
sysctl hw.usb.timings
If they are not there, possibly the USB_DEBUG option has been removed
from the kernel config. Can you check that?
