I am using 3.14.0 kernel version.

I compiled using localmodconfig.

I am using Ubuntu in my Lenovo U410 Ultrabook. I can use USB mouse,
keyboard, pendrives with the distro kernel 3.11.0-18-generic.

I can use USB mouse in distro kernel, but cannot use the same in compiled
kernel. I can plug in new pendrive in distro kernel and are automatically
mounted. But i cannot mount pendrive in new kernel. The same occurs for USB
keyboard. But i can mount Nexus 7 in both kernel.

Here is the output of dmesg and lsusb.
