New, and it looks to be an NF4 chipset level issue. You might ask ASUS what's up with it; that's a new board (got an extra one for me? :), and this could be something that's fixable with a BIOS update. They'll have more access to the NVidia errata than either of us, regardless!
I may send them an email about it, though whether anyone will read the bug report that can comprehend the problem is another matter :-)
This should either be cc=3 (with EHCI at 02:3 and two more OHCIs) or pcc=10 (or maybe cc=2 pcc=5, etc) ... and in your case it looks like the issue is that pcc=4 is wrong. NF2 and NF3 were cc=2 pcc=3, so I'm not sure how NVidia created that particular bug.
Yes, looks like it should be pcc=10 since there is one OHCI companion controller with 10 ports..
This patch should resolve the issue for you.
Indeed it does:
ehci_hcd 0000:00:02.1: reset hcs_params 0x10148a dbg=1 cc=1 pcc=4 !ppc ports=10
ehci_hcd 0000:00:02.1: reset portroute 0 0 0 0 0 0 0 0 0 0
ehci_hcd 0000:00:02.1: reset hcc_params a086 caching frame 256/512/1024 park
ehci_hcd 0000:00:02.1: capability 0001 at a0
ehci_hcd 0000:00:02.1: bogus port configuration: cc=1 * pcc=4 < ports=10
...
ub 1-0:1.0: USB hub found hub 1-0:1.0: 10 ports detected
That fixes the flash card reader, anyway.. Am also having problems with a Kingston USB pen drive in USB 2.0 in 2.6.10 however, will start a new thread about that one..
