Actually you cannot remap the USB settings IIRC, you will need to 
move the 2940 to another PCI slot. As said before, many boards 
have associated IRQ devices and it looks like in your case the USB 
shares IRQs with the PCI slot the adaptec resides in. You might 
wish to disable USB if you do not use it. You might wish to inspect 
the "PNP/PCI Configuration Setup" in your mobo Bios. The "INT 
Pin1(-4) Assingnment" settings that are set to "Auto" by default 
might show what devices are associatet with the PCI slots.

actually they run with 20MB/s, they run at 10MHz with 16Bit bus 
rsulting in the nominate 20MB/s. What you might to get are 40MB/s 
that is UW or 16Bit at 20MHz. resulting in 40MB/s. Check your 2940 
Bios settings, there is somewhere a "enable Ultra SCSI" setting you 
need to enable, IIRC that is a global setting, not a per device 
setting, but that might also be diferent for several BIOS versions.
