On http://linuxbios.org/EHCI_Debug_Port wiki page there is an info that Intel ICH4/ICH4-M chipset does not supports Debug Port. I have Dell D400 laptop with that chipset and Debug Port is available according to lspci output:
22:47 hrw@maluch:~$ sudo lspci -ns $(lspci|grep EHCI|cut -f1 -d' ');sudo lspci -vs $(lspci|grep EHCI|cut -f1 -d' ')
00:1d.7 0c03: 8086:24cd (rev 01) 00:1d.7 USB Controller: Intel Corporation 82801DB/DBM (ICH4/ICH4-M) USB2 EHCI Controller (rev 01) (prog-if 20 [EHCI]) Subsystem: Dell Latitude D400 Flags: bus master, medium devsel, latency 0, IRQ 11 Memory at faeffc00 (32-bit, non-prefetchable) [size=1K] Capabilities: [50] Power Management version 2 Capabilities: [58] Debug port
The ICH4 datasheet also says it has a EHCI debug port. Why is it not supported in LB?
Thanks - Joe

hardware (displays, data cables, automated profilers or such) are somewhat uncommon for it and the serial port / POST card is already quite helpful. the debug port could transmit much faster of course. so "someone should do it (tm)" (i.e. provide support) --Q

Support for the generic EHCI debug port already exists, IIRC it was necessary for the mcp55 port. The biggest reason we need this is that some boards don't have legacy serial ports any more, they rely on USB and port replicators/docks.

Fixed in the wiki, thanks!
I was the one who added the ICH4 in the wiki, but I don't remember which system I used to test that back then. Maybe I confused it with some other chipset or I was drunk or something ;-)

hmm, may system has no debug port:

so I think there are some different chips around. My is a rev 02 and Marcin one is a rev 01. Maybe that is the reason.

Did you both run the command as root (don't know, maybe it makes a difference)? But yeah, there could be differences between revisions...

yes, I was logged in as root.
