I just built U-Boot 2012.04 for the OMAP4 PandaBoard, hoping that

during the initial USB scan:
U-Boot 2012.04 (Apr 30 2012 - 18:08:55)
CPU : OMAP4430 ES2.2
Board: OMAP4 Panda
I2C: ready
DRAM: 1 GiB
MMC: OMAP SD/MMC: 0
Using default environment
In: serial
Out: serial
Err: serial
Net: No ethernet found.
Hit any key to stop autoboot: 0
Panda # usb start
(Re)start USB...
USB: Register 1313 NbrPorts 3
USB EHCI 1.00
scanning bus for devices...
At this point, it's dead - ^C does not work, nor does the RESET button.
Any ideas how I can get this working?
Interestingly, I unplugged the USB hub I had connected (in addition
to the built-in SMSC95xx ethernet) and now it works. It seems that
the USB scanning code is not very happy with either the hub or the
mouse+keyboard I had attached. I'll try to look into this later; for
now I'm happy that I can use the ethernet.
