mp3 players will not "connect" for charging

After updating to NIS2009, neither one of two players will "connect" when plugged in.  They have to be plugged in to usb port in order to charge.  The only thing that has changed has been the update to 2009.  Is there a setting in the firewall that has to be changed to allow this to happen?  If so, I've missed it.
