The xHCI driver does not support USB selective suspend right now. It's probably something I should fix, since most distribution kernels turn it on. You'll have to rebuild the 2.6.31.5 kernel with selective suspend turned off. > Please suggest me, how can I turn off the above feature in the > 2.6.31.5 kernel now.

I'm not sure what you're asking. If you have the source for the stable tree (at git://git.kernel.org/pub/scm/linux/kernel/git/hpa/linux-2.6-allstable.git), you can just go into that source tree, type make menuconfig and say 'N' to USB selective suspend. Then `make` and `sudo make modules_install install` and reboot into the newly compiled kernel.
