What kernel are you using?  If you're not using 2.6.14 or later, try 
upgrading before doing anything else.

It's hard to tell just what is going wrong without more debugging 
information.  If you turn on USB verbose debugging in the kernel 
configuration (CONFIG_USB_DEBUG) that may help indicate whether the 
problem lies in the drivers or in the device.

The fact that it works sometimes but not others indicates that it's a 
device problem.  On the other hand, if the device is bus-powered then it 
should reset completely every time you unplug it.
