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.
