Revision history [back]

You should probably track down, what the module did system-wide and undo that to see what is the problem. Following the link, there is a README that describes what was installed.

If there is a Kernel module included, you should probably remove that first for testing rmmod <module>, you can find the name by looking at lsmod.

Otherwise I have seen there are udev rules included, maybe they change the device somehow. If you remove them temporarily you can see if that fixes it. It should be possible to make compatible rules.
