00:07.0 ISA bridge: VIA Technologies, Inc. VT82C686 [Apollo Super South] (rev 40) Subsystem: ABIT Computer Corp.: Unknown device 0000 Flags: bus master, stepping, medium devsel, latency 0 Capabilities: [c0] Power Management version 2 50: 02 76 04 00 00 f0 ab 50 1f 06 ff 08 00 00 00 00

00:07.2 USB Controller: VIA Technologies, Inc. UHCI USB (rev 16) (prog-if 00 [UHCI]) Subsystem: Unknown device 0925:1234 Flags: bus master, medium devsel, latency 32, IRQ 5 I/O ports at a000 [size=32] Capabilities: [80] Power Management version 2 30: 00 00 00 00 80 00 00 00 00 00 00 00 05 04 00 00
