Public bug reported:
Hello,
Intel NUC D54250WYK, kernel 3.13.0-23-generic x86_64, Trusty 14.10,
package linux-firmware-nonfree 1.14ubuntu1
Installed and updated trusty 2 days ago, also updated select libs
yesterday trying to debug this issue. Issue seems to be with firmware
load and the usb subsystem. When Hauppauge 950Q inserted to usb port,
kernel sees it and reports what appears to be normal device recognition.
As soon as an application tries to access the Hauppauge device, there
are problems. Two examples can make it fail repeatedly.
Fail case #1)
With Hauppauge inserted into usb port, as root, run lsusb -v
it aborts when trying to ennumerate the Hauppauge device.
Bus 002 Device 004: ID 2040:7200 Hauppauge
lsusb: gconv.c:74: __gconv: Assertion `outbuf != ((void *)0) && *outbuf !=
((void *)0)' failed.
Aborted (core dumped)
This failure is non-harmful as the USB bus is still active and devices
plugged into usb still function.
Fail case #2)
With Hauppauge inserted, run VLC and choose to capture the video device.
VLC runs, kernel reports the firmware load starting, and completing. As
soon as firmware load completes, the USB bus and all devices plugged in
there are cut down. Unplug and replug USB devices has no effect, and
additional usb plug events are not seen or reported by kernel. Power
off to recover.
Tried debugging a little. The linux-firmware-nonfree package provides
dvb-fe-xc5000-1.6.114.fw, but the kernel asks to load a newer version,
dvb-fe-xc5000c-4.1.30.7.fw. I got newer version from kernellabs.com and
tried it. Behavior is the same.
Note- this device is known to work. I have it working in ubuntu 11.10
32bit, and in ubuntu 12.04 64bit.
My kyb, mouse, and network card are all usb. Do not have a wired
ethernet connection to gain access (via ssh) after usb goes away.. Will
get that today but I don't know where to focus debug effort next.
Gladly assist with additional debug.
