Hello,
I was just reading the LinuxBIOS pages and saw that you wanted reports on debug port capability of USB 2.0 controllers.
I have a VIA SP13000 motherboard that wasn't listed and doesn't have the debug port capability:
lspci -v: 0000:00:10.4 USB Controller: VIA Technologies, Inc. USB 2.0 (rev 86) (prog-if 20 [EHCI]) Subsystem: VIA Technologies, Inc. USB 2.0 Flags: bus master, medium devsel, latency 176, IRQ 11 Memory at ec000000 (32-bit, non-prefetchable) [size=256] Capabilities: [80] Power Management version 2
lspci -n: 0000:00:10.4 0c03: 1106:3104 (rev 86)
I hope this helps!
Regards, Wander Winkelhorst
