^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30)  A:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31)     Go to your BIOS setup, section PCI devices or similar.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32)     Turn USB support on, and try again.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37)  A:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38)     This can happen. This driver uses the pins VIA recommends in their
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39)     datasheets, but there are several ways the motherboard manufacturer
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40)     can actually wire the lines.
