Either the USB stick is for some reason only recognized as a read-only media or the ext file system implementation decides that it's not a good idea to provide write access. You could easily rule out the former by dd'ing the stick (respectively the partition on it, if that's how it is formatted) to an image file and try to mount that. At any rate please open a Trac ticket. CU, Ingo
