Did you make sure you have the proper driver for the webcam your using? That
would be the first place to check. also right after you plug in you cam try
dmesg | tail and that should show possibly some other info, I was able to
get one webcam of mine to work plug and play but my other cam did not work
this way and the driver it needs I cant get to build yet.

Just a beginner trying to learn his way around.

There are, as far as I can tell, four possible issues:
1) The camera you are using needs more power than the gumstix usb port can
provide. Desktops and laptops can provide this power, but Gumstix cannot.
The solution is to buy a powered, high speed (EHCI) USB hub. Not all
cameras will need a powered hub. I have successfully used a Logitech webcam
plugged directly into a Tobi USB port.
2) Despite what you might think, the driver might not be correct.
3) You have somehow damaged the USB port on the Tobi. I did this. Confirm
it is still functioning by trying other devices. A flash drive is a good
4) The camera you are using is not a "high speed" USB device (USB 2.0 or
EHCI are a couple of alternative names for high speed USB). Desktops and
laptops will work with any type of USB device, Gumstix only works with High
Speed devices. If this is the problem, then once again you will need a High
Speed powered USB hub. I have also experienced and fixed this problem with
a Tobi board and a Belkin 7-Port USB hub.
