This is just a patch for the problem reported here: http://lists.denx.de/pipermail/u-boot/2012-February/117580.html originally reported by Igor.
"Looks like this is copy paste error from my side,(for port2/3 it should have been bypass for port2/3 rather its port1 set in bypass mode)"
I only submit the patch since it is missing in 2012.04-rc3 while the twister board depends on it. Maybe it is already somewhere in the reposistory, but I cannot find it.
note: the twister boards still needs an additional `usb reset`, don't know why.

Yes it was a typo and Looks like the corrected patch was not picked up as in here: http://permalink.gmane.org/gmane.comp.boot-loaders.u-boot/124620
