0025 ---------
0026
0027 Q:
0028 You have VT82C586B on the motherboard, but not in the listing.
0029
0030 A:
0031 Go to your BIOS setup, section PCI devices or similar.
0032 Turn USB support on, and try again.
0033
0034 Q:
0035 No error messages, but still i2c doesn't seem to work.
0036
0037 A:
0038 This can happen. This driver uses the pins VIA recommends in their
0039 datasheets, but there are several ways the motherboard manufacturer
0040 can actually wire the lines.
