This may be slightly off-topic. If it is, I apologize in advance.

I recently got a docking station for my Gateway Solo 5300 laptop and
I'm experiencing problems with it. I don't know if it's a hardware
problem or a driver issue, as I've only used the docking station with

I know the PS/2 ports and the monitor port on the docking station
work, as I'm using them right now. The USB ports, the PCMCIA ports,
and the sound jacks don't work, even from a cold boot with the laptop
docked. If I plug a PCMCIA card into the slots on the docking station,
I get nothing. If I plug the same card into the slots on the laptop,
the card works, even though the laptop is docked. The same applies to
the sound jacks.

I'd just use the USB port on the laptop, as I have a feeling it would
work in light of this experience, but the USB port is in the back of
the laptop, so it's physically inaccessible while the laptop is

Below is the verbose output of lsusb while the laptop is docked. The
two ports on the docking station seem to be recognized and just not
getting power. Are there any further tests I can do to determine if
it's a gNewSense-specific issue or if it's a hardware issue?
