Scanner no longer works with my AMD PC

[David Fletcher]

Is anybody else seeing any problems such as this? At first I thought the
scanner had died on me. I added my notes to launchpad bug #1250196 as it
seemed like the most appropriate one to contribute to:-

I'm using an Epson Perfection 2450 Photo, which some time ago I thought
had gone wrong because it suddenly stopped working with my desktop
computer. When using xsane it finds the scanner OK, then when I try to
get a preview it puts up an error message:- "Error during read: Error
during device I/O". Damn.

When I lspci on the desktop computer I get (pruning out everything other
than the USB parts

00:02.0 USB controller: NVIDIA Corporation CK804 USB Controller (rev a2)
00:02.1 USB controller: NVIDIA Corporation CK804 USB Controller (rev a3)
.
.
01:07.0 USB controller: NEC Corporation OHCI USB Controller (rev 41)
01:07.1 USB controller: NEC Corporation OHCI USB Controller (rev 41)
01:07.2 USB controller: NEC Corporation uPD72010x USB 2.0 Controller
(rev 02)
02:00.0 USB controller: VIA Technologies, Inc. VL80x xHCI USB 3.0
Controller (rev 03)

Now it gets really interesting. If I plug the same scanner into my
little 10" Toshiba laptop, it works perfectly. Both computers are
running 64 bit Mint 17/Mate.

I think the crucial difference might be in the hardware When I lspci on
the laptop the USB controller lines all say
Intel Corporation NM10/ICH7 Family USB UHCI Controller#1-4 (rev 02)

So maybe the problem is actually with a USB driver? Intel has a
reputation for being better supported than other hardware.

No response to my bug report yet, so I thought I'd ask here as Mint is
pretty much Ubuntu but the mailing list is far more active.
