Comment 665 for bug 88746

I have similar issue with 2.6.29 I hadn't before (in 2.6.28 - however it might be so as modules used to be loaded in incorrect order by udev):
[250625.112100] usb 3-4: reset high speed USB device using ehci_hcd and address 2
[250640.646029] usb 3-4: device not accepting address 2, error -110
[250640.748038] usb 3-4: reset high speed USB device using ehci_hcd and address 2
[250656.288076] usb 3-4: device not accepting address 2, error -110
[250656.390089] usb 3-4: reset high speed USB device using ehci_hcd and address 2
[250666.812036] usb 3-4: device not accepting address 2, error -110
[250666.914045] usb 3-4: reset high speed USB device using ehci_hcd and address 2
[250677.336026] usb 3-4: device not accepting address 2, error -110

It is a single USB stick connected to port. When I'll have free time I'll check a) verbose output b) 2.6.28.
