     24Problems?
     25---------
     26
     27 Q:
     28    You have VT82C586B on the motherboard, but not in the listing.
     29
     30 A:
     31    Go to your BIOS setup, section PCI devices or similar.
     32    Turn USB support on, and try again.
     33
     34 Q:
     35    No error messages, but still i2c doesn't seem to work.
     36
     37 A:
     38    This can happen. This driver uses the pins VIA recommends in their
     39    datasheets, but there are several ways the motherboard manufacturer
     40    can actually wire the lines.
