I recently downloaded new linux kernel source code and compiled on ubuntu. After my system is not recognizing any usb devices. Is there any changes required to compiling procedure or make files in order to enable USB host?
Please help me to get out of this problem. Thanks.
It is possible for the USB support to be disabled though incorrect or incomplete configuration.
You didn’t mention how you configured the kernel though.
A good point to start is the existing configuration for the default Ubuntu kernel. There should be a config file in boot, like
/boot/config-3.1.0-1-amd64.Copy that file to your kernel directory as
.config, then usemake oldconfigto update the configuration.When installing the kernel take care to create the corresponding initrd as well.
