This is the kind of issue that made me create this (discarded) patch at some point: http://patchwork.ozlabs.org/patch/176527/
Can you try it? I'm not sure that it will be helpful for your specific case.
I also have this issue with some devices and mainline U-Boot. I can confirm that this is a device initialization delay issue because subsequent USB commands on the device succeed (only the single automatic U-Boot USB command that I use at boot time fails).
FWIW I've had a similar problem with an OMAP3 board. I run "usb start" and then immediately "usb reset" once or twice until my USB device shows up.
I'll try the suggestions here.
