Also I think it's just a little miswording (or extended typo), I'm not 
using a regular USB cable, but an OTG cable when using the host mode of 
the musb on the Beagleboard. Just to avoid confusion. Or do you talk 
about the client mode when it goes to 2?

Besides that, I'm sorry to not be of further help. My deeper knowledge 
about the musb sources in the kernel and u-boot (and the HW in 
question), has gone lost and I've currently no real reason to refresh 
that. ;)
