it's a pci usb 2.0 card. no active device plugged there.
i compiled ehci and uhci as module and now i can suspend after unloading both.
this is the only problem i have.
What version of Linux are you using?
2.6.14-rc2-git3 (today's one)
What happens if you rmmod ehci-hcd and leave uhci-hcd loaded?
i wrote in the dmesg:
eth1: Setting promiscuous mode.
uhci_hcd 0000:00:0a.1: HC isn't running!
hub 3-0:1.0: PM: resume from 1, parent usb3 still 1
hub 3-0:1.0: hub_port_status failed (err = -113)
hub 3-0:1.0: hub_port_status failed (err = -113)
hub 3-0:1.0: activate --> -113
hub 3-0:1.0: hub_port_status failed (err = -113)
hub 3-0:1.0: hub_port_status failed (err = -113)
Some devices failed to suspend
What do you get in the system log if you turn on CONFIG_USB_DEBUG?
Alan Stern
actually i haven't debug enabled.
in my dmesg you can see reactions to these operations:
a) suspend
....it fails due to ehci
b) remove ehci
...if fails due to uhci
c) remove uhci.... works!
after i resume and reload both modules.
