Hi, I'm going to lump a bunch of things into one email to save your patience.
kernel: 2.6.13 SMP
First, my PCI card probes as ehci but doesn't really seem to work very well:

However, if I "rmmod ehci-hcd" and then "modprobe ohci-hcd", nothing happens
Then, if I remove and re-insert the device, it sees it:

What's the deal? Anyone got any tips?
I can work-around by uncommenting this:
# tail -n 1 /etc/modprobe.conf
#alias ehci-hcd ohci-hcd
However, that's pretty ugly.
Also, sometimes I get these:
Nov 17 04:43:12 hostname kernel: drivers/usb/input/hid-core.c: control
queue full
Do I care?
Thanks for any pointers,
