Now, I've just upgraded it to kernel 2.6.22. The modules seem loaded fine, please see following list, but neither USB nor MMC could detect devices when a USB stick or SD card was plugged in (I enabled module debug, but nothing printed out, no device node created in /dev). It seems some processes were not running, but I can see usbd and mmcd were running at following list, or what is missing?

I manually created nodes on /dev tree such as /dev/mmc /dev/scsi before building and downloading to the target. Any clues please?
