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.

39    datasheets, but there are several ways the motherboard manufacturer
