Thanks for the suggestion. I'm sort of aware of these VIA vs. USB trouble.
A friend of mine has a mass-storage stick for USB, but his FreeBSD hangs
when unmounting this device. He has a VIA chip. I don't so the mass-storage
stick works with my FreeBSD!

Here is what I have; grep "USB controller" /var/run/dmesg.boot:

uhci0: <Intel 82801EB (ICH5) USB controller USB-A> port 0xbc00-0xbc1f irq 2 at device 29.0 on pci0

Would you still recommend this with above chip?
(What is my BIOS? Can I find out without having to reboot....?)

I try not to blame anyone; I was confused and frustrated by the fact that
my collegues use the same scanner on a Windows box and have it setup in matter
of minutes, without a hitch. I'm struggling for days, and still it hardly
works properly.
