| 23 | ||
| 24 | Q: You have VT82C586B on the motherboard, but not in the listing. | |
| 25 | ||
| 26 | A: Go to your BIOS setup, section PCI devices or similar. | |
| 27 | Turn USB support on, and try again. | |
| 28 | ||
| 29 | Q: No error messages, but still i2c doesn't seem to work. | |
| 30 | ||
| 31 | A: This can happen. This driver uses the pins VIA recommends in their | |
| 32 | datasheets, but there are several ways the motherboard manufacturer | |
| 33 | can actually wire the lines. | |
