usbduxsigma_firmware.bin: old version causes driver crash
Status in linux-firmware package in Ubuntu:
Status in linux-firmware source package in Xenial:
Impact: The usbduxsigma firmware is out of date and causes the driver
to fail. This is fixed by updating the firmware from upstream linux-
Test Case: Using the driver with the old firmware fails. Using it with
the new firmware does not.
Regression potential: The firmware is only used by the one driver so
there is no potential for regression anywhere else, and the driver
already isn't working with the old firmware.
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.
