Problem Description:
I've connected a mouse and a Canon MP600 (multifunction device) on a mini hub 
which is then connected to the mainboard (USB2.0). Nothing is working on the 
mini hub because of the initialization problem.

syslog output is:

Problem Description:
I've connected a mouse and a Canon MP600 (multifunction device) on a mini hub 
which is then connected to the mainboard (USB2.0). Nothing is working on the 
mini hub because of the initialization problem.

syslog output is:

Comment 2 Alan Stern 2007-02-05 11:02:26 UTC

You said that this problem doesn't occur in 2.6.18.  Can you provide a dmesg log
showing what does happen with that kernel?  It would help if you turn on
CONFIG_USB_DEBUG before building the USB drivers.

Also, for 2.6.20, please get a usbmon log.  Instructions are in the kernel
source file Documentation/usb/usbmon.txt.

Comment 4 Martin Bammer 2007-02-05 12:35:47 UTC

Created attachment 10295 [details]
dmesg of kernel 2.6.18.6

Comment 5 Alan Stern 2007-02-14 09:26:06 UTC

The usbmon log shows clearly what the problem is.  You have the mini-hub plugged
into port 4 of the motherboard's EHCI controller, and you have some other hub
plugged into port 3 of the EHCI controller.  That other hub doesn't have any
devices attached to it, so the kernel suspends it.

Then the problem starts.  When port 3 is suspended, port 4 stops working also. 
This must be a hardware bug in your motherboard's EHCI controller.  You could
try working around it by moving the other hub to a different port or removing it
entirely.  Alternatively, you could prevent the other hub from being suspended
by doing:

    echo disabled >/sys/bus/usb/devices/1-2/power/wakeup

or by turning off CONFIG_USB_SUSPEND in your kernel's configuration.

Comment 6 John Zero 2007-06-12 01:11:58 UTC

Many others have experienced this bug, see this entry:
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/88746

This bug was certainly not present in the previous Ubuntu release kernel (2.6.18 ???) only in the current (2.6.20)

Comment 7 Alan Stern 2007-06-12 10:01:15 UTC

Your comment is a little mystifying.  The bug isn't present in any kernel, Ubuntu's or anyone else's.  The bug is in the EHCI hardware on Martin's computer.

Comment 8 John Zero 2007-06-12 13:31:03 UTC

Sorry, please disregard my comment!

I accidentally thought this but is the same as the Launchpad Linux kernel ehci_hcd bug (the URL I linked.) Oops.

It sounds like the problem was resolved, probably time to close the bug.
