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
