[U-Boot-Users] u-boot 1.1.1 and USB mass storage devices

Hello,

We are using u-boot on a Samsung S3C2410 based board and have USB mostly working using the arm920t USB driver. I say mostly working as some mass storage devices work fine, but most do not.

Typically the behavior we see when they don't work is a "usb reset" reports the correct number of devices, a "usb tree" will return the correct device tree but "usb scan" will typically return a lot of CLI:TIMEOUT errors and seemingly never return. Sometimes it is able to find the storage device, but reading from it (it has a FAT16 filesystem) will return similar errors.

I'm curious if these are known problems or likely to be something in the way we have (or have not) set up usb? Might anyone have some recommendations as to where to start looking?

Thanks for any help!

Shannon
