Subject: PR/47522 CVS commit: src/sys/dev/usb
Date: Sat, 7 Sep 2013 16:17:12 +0000

 Module Name:   src
 Committed By:  skrll
 Date:          Sat Sep  7 16:17:12 UTC 2013
 Modified Files:
        src/sys/dev/usb: uhci.c
 Log Message:
 Deal with control transfers better by
        - removing the UHCI_PTR_VF flag for the setup and status stages
          which means they are scheduled less aggressively.  Some devices
          appear to require this (blymn@ has one).  The flag was
          introduced as a performance improvement for bulk transfers.
        - Checking for short reads and making sure the status stage runs
          if they're encountered.
 PR/47522 Enumeration of LUFA/Atmel devices on UHCI fails
