Problems?

Q:
You have VT82C586B on the motherboard, but not in the listing.
A:
Go to your BIOS setup, section PCI devices or similar. Turn USB support on, and try again.
Q:
No error messages, but still i2c doesn’t seem to work.
A:
This can happen. This driver uses the pins VIA recommends in their datasheets, but there are several ways the motherboard manufacturer can actually wire the lines.
