Based on my fading understanding of that "driver"'s source code, this
**should** be taken care of automatically by the driver.

Please submit an issue at


which is a Community Code Base fork of the upstream you installed that I
still somewhat "maintain" in my free time.

When you do, please include your device's USB product ID (lsusb should
tell you what it is) and the distribution you use.
If you feel adventurous, clone the code and build from source (see the
README for instructions, build takes a while and may require up to 2GB
of RAM!) and attach a log to your issue.

Hope this helps,
