I think the new code depends on kproc_exits which is introduced in 
src/sys/kern/kern_kthread.c Revision 1.40,
but this version is only in -current.
Also I saw that there is a fix for freebsd 6.X in 
i4b/trunk/i4b/src/sys/dev/usb/usb_port.h at line 197:
#if (__FreeBSD_version >= 700000)
But at version 700055 (releng_7_0 from today) kproc_exec() is still not 
introduced, so the build failed.

I tried to compile by changing few lines to:

#if (__FreeBSD_version >= 800000)
#define usb_thread_create(f, s, p, ...) \
                kproc_create((f), (s), (p), RFHIGHPID, 0, __VA_ARGS__)
#define usb_thread_exit(err)    kproc_exit(err)
#elif ((__FreeBSD_version >= 700000) && (__FreeBSD_version < 800000))
#define usb_thread_create(f, s, p, ...) \
                kthread_create((f), (s), (p), RFHIGHPID, 0, __VA_ARGS__)
#define usb_thread_exit(err)    kthread_exit(err)
#else
#define usb_thread_create(f, s, p, ...) \
                kthread_create((f), (s), (p), RFHIGHPID, 0, __VA_ARGS__)
#define usb_thread_exit(err)    kthread_exit(err)
#define thread_lock(td) mtx_lock_spin(&sched_lock)
#define thread_unlock(td) mtx_unlock_spin(&sched_lock)
#endif

But I'm now stuck at:
