Let the bits speak
After I re-compile my kernel using a vanilla one, I found that my usb flashdrive can not be detected by my operating system. I check on dmesg, there are entry about my usb flashdrive on the log:
In order to doing some research in operating system, I need to build Linux kernel from source. Although my GNU/Linux distro provide Linux kernel package which ready to use, I can not use it for Linux Kernel development. It is recommended to be able build my own Linux kernel in order to customize my build.
