Sorry, deleted a duplicate account under which this was originally written.
I re-entered the question under the right account now, and deleted the duplicate account.
so:
Are there any known USB issues with GA-B75M-D3H rev 1.1 motherboard?
Can anybody give me any hints about how to find out what's going on with the USB?
My problem showed up as a printer issue, but it seems that the problem is more related to USB.
I've tried Debian 7.1, - 7.4, some ubuntu distro (don't remember the release) and a couple of Linux Mint distros (13, 15, 16, both 32 and 64 bit) without any luck. Tried several USB-ports too (no hubs or anything in between).
Even flashed a new BIOS (F15), but it didn't help. (the old one was F11)
The printer is Canon Pixma MP140 which every distro has recognized fine.
Usually the printing starts fine, but after page or two it slows down to one head sweep per 10 mins, or it stops on the last page totally (and needs power cord reset to recover).
With the Linux Mint 16 Cinnamon 64-bit live-DVD þe printing slowed the end of the last full page (one line per 10 minutes) and at the end
(on the last page containing just a couple of lines) the printing stopped altogether leaving a paper in.
With the exactly same live-DVD on my laptop it printed fine.
(Fujitsu-Siemens Amilo Li 2735)
I tried (GA-B75M-D3H board) with both USB 3.0/2.0 and USB 2.0/1.1 ports and same problem with both.
The printer is this far the only thing that has problems. Webcam and USB memory sticks work fine, and so do
my android phone and camera through an USB cable.
