Hello everybody, on recent kernels, my dvb usb device does not work any more and crashes khubd when I remove it. It has worked perfectly on wheezy and works perfectly in Windows, so it is no hardware failure. Since I do not know a lot about the kernel internals I have no idea how to debug this. Can somebody help me with this?
When the device is plugged in, it is recognised by the kernel as the
output of dmesg shows:
[ 1162.196344] usb 8-3: new high-speed USB device number 2 using ehci-pci

However, no program can open those devices:

Failed to open frontend
Being root does not help, my normal user is a member of the group video.
Sometimes, and I do not have a clue when, the device works for some
reason. Last time it worked was when I upgraded from kernel
3.16.7-ckt2-1 to 3.16.7-ckt4-3 and I thought the issue was gone, but it
was not. Sometimes, after a reboot, it works perfectly again.

The lsmod output shows that dvb_usb_dib0700 is in use by something, but
the device files are not opened by any process:

The same happens when I just unplug the device instead of (forcing) a
module removal, but I did not yet check whether all the hexadecimal
numbers are the same in both cases. These messages are repeated every
120 seconds.
lsusb and lspci output is at the bottom of the mail.
Complete kernel version:
$ cat /proc/version
Linux version 3.16.0-4-amd64 (debian-kernel@lists.debian.org) (gcc
version 4.8.4 (Debian 4.8.4-1) ) #1 SMP Debian 3.16.7-ckt4-3 (2015-02-03)
For some strange reason, this issue even affects Icedove: Before the
khubd crash, I can send email. After the crash, clicking on "Send" just
does nothing. Only a reboot corrects this. Checking for new mail via
IMAP works.
Thanks for your help in advance!
Sincerely,
Tilman
