Hello Alan,
Sorry for the wrong information,
but i am using linux kernel 2.6.11.8
still i am getting the timeout errors like following

1-1: khubd timed out on ep0in
usb 1-1: device descriptor read/64, error -110
usb 1-1: khubd timed out on ep0in
usb 1-1: device descriptor read/64, error -110
usb 1-1: new high speed USB device using ehci_hcd and address 3
usb 1-1: khubd timed out on ep0in
usb 1-1: device descriptor read/64, error -110

Is the usb stack bug in this kernel also
or
