If the kernel's got a driver set up for the device, then you have to
tell the kernel
to let go before you can set the configuration etc.
I forget the API function, but it's obvious if you look.
Also you probably need to do this as root.
Does it mount as a serial to usb device, I wonder, or a filesystem?
Have you used 'lsusb -v'?
If it's one of those two, you've got a better chance of getting data
out of it than if they've gone and implemented a custom USB device.
good luck!
