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. ;) Regards, Alexander Holler
