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 | |
| 1da177e4 LT |
39 | datasheets, but there are several ways the motherboard manufacturer |
| 40 | can actually wire the lines. |
