Default [Help] Unmounted Internal SD, Remounted, but USB not working

Hi everyone,

I used external 2 internal root to swap my USB flash drive with the internal storage, however, there was once whereby i accidentally unmounted the internal storage, thinking that it was the flash drive

now, whenever i boot up with the flash drive plugged in, i will see 2 USB flash drives as the internal, and mounted USB drive

when i plug out the flash drive and boot, it will show the internal drive, how do i mount back the internal drive?

ok guys, update

i managed to boot into CWM and mount back my internal SD

problem now, my USB port is totally dead, i can't mount back my flash drive, nor can i power my keyboard

any one can help?
