           Summary: RNDIS Ethernet Gadget fails on Windows with Linux

    Classification: Unclassified

           Version: unspecified
          Platform: ARM
        OS/Version: Windows NT/2000/XP
            Status: UNCONFIRMED
          Keywords: patch
          Severity: minor
          Priority: P3

The Linux RNDIS Ethernet Gadget is the name of the Windows driver used to
connect to a Linux machine by USB. This always fails ("This device cannot start
(Code 10)") using the 2007.12 distribution of Angstrom. The following page
claims this is due to a bug introduced into the Linux kernel between 2.6.22 and
2.6.24. It provides a patch that is said to solve the problem (which only
affects Windows hosts). I've included the patch separately below.
