solves problem of hanging usb sessions with cams using gphoto2 ptp2 driver
- bumped port revision
- tested by different people under -current and -stable, no ill side
effects and really cures the problem.
The author of bsd.c clearly states out in the sources, that he
has ported codee from linux 1:1 and he "kind of hopes" that it is ok.
But it wasn't.
This patch fixes hang that happens after the 1st read because the USB
driver tries to read more bytes than are available.
