Hello,
I am trying to use u-boot on my raspberry pi model B to boot Linux from a usb drive. I followed instructions from http://elinux.org/RPi_U-Boot with the mainline git master branch since going through the commit log quickly it seems that usb support was added. Unfortunatly it seems that my usb drive is not detected by uboot. Here is the error I get: usb_new_device: Cannot read configuration, skipping device 058f:6387
Full log: ============================ U-Boot 2015.07-rc1-00148-g4588d61 (May 16 2015 - 18:11:32)

So usb must be somewhat working since the ethernet port seems to be detected, but not the drive. Am I missing some configuration or is usb storage for rpi just not available yet?
Thanks
