The linux firmware has been updated and the usbduxsigma firmware as
well. However it's still the _old_ firmware.

usbduxsigma_firmware.bin: old version causes driver crash
Status in linux-firmware package in Ubuntu:
The firmware of the usbduxsigma (alongside with the usbduxsigma.c) was
updated in 2015 during a major rewrite but its binary was still the
old one which causes the kernel driver to fail.
I've submitted a patch to the kernel people (see below).
However, as a quick fix could you also apply the patch to the package
directly to have this fixed now and then we can wait until it trickles
down from the kernel.
I'm the maintainer of both the firmware and the drivers.
This affects both 32 and 64 bit distros.
