You will need to provide much more information then that. What does
dmesg say? lsusb? what driver are you using, what kernel version? Are
you using it as a module? Have you enabled debugging in your kernel?

Those questions come to my mind.

Paste your logs (or if its too much, only copy/paste the relevant parts.
You ask for a limb, yet offer nothing.
