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.

connect all your usb devices, reboot to the uduntu precompiled kernel, be sure that all modules are loaded and all devices are working properly, then again do "localmodconfig" and re-compile a new kernel.
