But, its probably not the same motherboard/chipset combo on that
motherboard. This duck walks and quacks exactly like one of mine,
an older TYAN S-1590 motherboard, with an early via chipset driving
its usb headers.
This 82C586 (IIRC) chipset can *usually* handle a usb mouse, only
losing it after 2 or 3 months uptime. Most of the time its fine.
But move my 1250 to one of its plugins, and build sane on it and
VIA's inability to really build a usb right the first time will be
demonstrated. All the tests will work just fine, so you fire up
xsane and actually try to do a scan and you rapidly find, usually
within the first megabyte downloaded from the scanner, that the
machine is hung so tightly that even the toolbar clock is stopped,
and that the machines only response to anything is the hardware
As ext2 doesn't like that, and neither does reiserfs, usually
requireing that the drive be fscked and the os re-installed, after
doing that 4 or 5 times I gave up. The scanner sat there looking
smug and saying 'Gotcha'.
About that time I decided to build a faster machine using a
different motherboard, this time a Biostar M7VIB. When it was up
and running I moved the scanner cable to one of its usb ports,
installed the exact same version of sane by copying the src's over
a samba link and recompiled it. Over about half the life of
sane-*-1.x now, its worked exactly as Gerhard wrote the code to
make it do, and at the moment I'd use it for production if I had
any. And its never locked the machine up.
The Moral is that some machines usb hardware is so broken there is
no hope of running a scanner on one of them. That early 1998 TYAN
mobo is one in that category.
