I have on 2 out of about 20 assorted USB 802.11g radios I've dealt
with. One was a Dlink WUA-1340 that sorta claims to be 1.1 compatible
with:
http://www.dlink.com/products/resour...rid=1824&sec=0
"Using a USB 1.1 port will affect device performance." When I tried
it on an older Dell laptop (forgot the model number), it installed,
ran, and did all the right things but at 11Mbits/sec maximum. However,
over a period of a few weeks, the customer started experiencing some
problems. It often not recognize the USB device on reboot. It it
were accidentally unplugged, it would not recover gracefully and had
to be power cycled. It had the habit of locking up when coming out of
hibernate and standby. The problem was that it was very erratic.
When I played with it and tried to reproduce the symptoms, it would
only do these things perhaps about 20% of the time. Weird.

So, I shoved in a USB 2.0 PCMCIA card. The customer wanted one anyway
for his external USB hard disk backup contrivance. I plugged the
WUA-1340 into the USB 2.0 card, and everything has been working just
fine for about 2 weeks.

Now, I'll grant that there's a good chance that this was due to some
USB chipset oddities or driver problems, but I also had a DLink
DWL-G122 do much the same thing with a USB 1.1 port (although far less
often).
