Thanks hippo!

while looking for guides about porting over drivers, i found this for the 2.6.x distribution

http://blackfin.uclinux.org/plugins/scmcvs...root=uclinux533 (http://blackfin.uclinux.org/plugins/scmcvs/cvsweb.php/uclinux-dist/linux-2.6.x/drivers/usb/host/?cvsroot=uclinux533)

not sure if any changes need to be made since the hardware is different from blackfin? (in the header files)

i&#39;ve tried plugging in a usb flash drive but nothing happens after trying:

1. in root fs, you need some scsi dev nodes, eg sda, sda1... to use mass storage dev

you need usbfs, too. I have setup them in the post of buildroot guide, so they are ready.

2. in kernel menuconfig,

turn on file system support, eg, vfat and native lang codepage 437

turn on scsi device, scsi disk

turn on host-side usb, usb dev fs, your hcd, usb device eg mass storage.[/b]

for 1. do i need to do anything else for sda and sda1? - usbfs seems to be registered

for 2. i&#39;ve enabled all of those options.

sorry about the huge post but thx in advance!
