A quick look shows a bunch of changes were MFC'd in 11 days ago and other than that, nothing has changed in the USB area for a while. I'm not an expert at tracking these things down though so I could have missed something.

USB is broken.

Hi,

If you don't see a panic prompt, then you need to use an external USB 
HUB with own power supply to avoid that. I've just MFC'ed the last DWC 
OTG related patch from -head:

http://svnweb.freebsd.org/changeset/base/267039

Can you build a new kernel including that patch. BTW: You only need to 
build a new kernel, you don't need to install a new userland.

Can you show dmesg for the attach failures?
