[sane-devel] IRQ conflict between Fujitsu fi-4120c and NIC

[m. allan noah]

scanner does not use an irq, but the usb host adapter built into your 
motherboard does. at system boot time, the irq assigned to different 
devices can be changed by the bios.

try going into your bios and set 'plugandplay os' to no. that usually 
helps. if not, try manually setting irqs for different devices in the 
bios.
