Not sure... I only know that punk.kaos's Froyo version has come a long way, but is still a work-in-progress (v24), but I don't see anything about USB not working in the thread on XDA...
Perhaps you could post in that thread ([ROM]KaosFroyo V24 [07/21] [FROYO] - xda-developers) a question and see if anyone over there is having the same issue? I'm not a Mac guy (my daughter is, but she's got her Macbook at college), so I'm a little handcuffedre. this.
Good luck!
+1 thats exactly what I would've posted, thanks scary alien
