Package: usb-modeswitch
Version: 2.2.0+repack0-2
Severity: normal
Tags: d-i
Dear Maintainer,
* What led up to the situation?
The default IOMMU setting in the BIOS for a GIGABYTE motherboard is off.
Attempting to install a Debian system (Wheezy or Jessie AMD-64) with this
setting results in not recognizing USB mouse or keyboard. However, booting with
Squeeze or Wheezy 386 does work with this setting.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Turned on the IOMMU support
* What was the outcome of this action?
Although the USB-2 mouse and keyboard are dealt with effectively with IOMMU
enabled, there are ~550 lines of "page fault" reported by dmesg at bootup.
Further investigaiton finds that failure to access the northbridge (AMD 970
chip) USB-3 support is the cause of the page faults.
* What outcome did you expect instead?
Everything to work

Hi,
this bug was filed for an old version of the package and the kernel and
probably already fixed in a later upload.
If you can reproduce it with the current version in unstable/testing
please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.
Best regards,
Thorsten
