Greetings,
I'm porting 2.6.29 to our ARM9 (Micrel KS8695) based box. For USB
connections VIA VT6212 controller is attached to the PCI bus. If
connecting a card reader I get following error message concerning no-IRQ:
ehci_hcd 0000:00:06.2: port 2 high speed
ehci_hcd 0000:00:06.2: GetStatus port 2 status 001005 POWER sig=se0 PE

usb 1-2: new high speed USB device using ehci_hcd and address 2

ehci_hcd 0000:00:06.2: Unlink after no-IRQ? Controller is probably using
the wrong IRQ.

This message may be right. Are you getting any interrupts from your
EHCI controller?
You're right. CPU pin was not activated as IRQ source. I was thinking
the problem was HCD, but the real problem was at the lower level. Thank
you very much for your help.
