That's the DWC_OTG driver. It's BSD-licensed (or nearly so) in Octeon Linux, but probably GPL tainted in at least a few places. Someone was working on porting it to FreeBSD, but I believe they abandoned that approach in favor of writing a driver from scratch. It should be easy enough to port to FreeBSD, although I understand that Elite USB Hackers probably wouldn't find a from-scratch driver very difficult given the amount of code-as-documentation that's available in that for. Good luck!
