USB Host problem caused by u-boot

Hi,

My beagle is rev. B7. I'm using USB OTG in host mode (pin 4th
connected to pin 5th in USB socket). If I use preinstalled u-boot ( U-
Boot 1.3.3 (Jul 10 2008 - 16:33:09) ) USB works fine (or rather with
small problems like not seeing usb hub if it wasn't restarted if
beagle was). If I build new u-boot (OE, u-boot_git.bb) USB stops
working. Nothing happends when I'm connecting hub etc.

lsusb gives:
Bus 001 Device 001: ID 1d6b:0002
Bus 002 Device 001: ID 1d6b:0002

I'm using my own Angstrom builds from git tree.

Have you got some ideas/advices how to solve it? I need new u-boot
becouse I've placed there pin muxing for SPI (it's not the reason of
usb problem, chacked).

Regards,
Robert
