           Summary: cdc_ether bad CDC descriptors with Samsung Galaxy S
                    and Android >= 2.3.4
    Classification: openSUSE
           Product: openSUSE 12.1
           Version: Final
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Major
          Priority: P5 - None
         Component: Kernel
        AssignedTo: kernel-maintainers@xxxxxxxxxxxxxxxxxxxxxx

The kernel module doesn't detect the tether hardware from Samsung Galaxy S
after updating to Samsung Android version to 2.3.4 or 2.3.5.
lsusb reports with the new versions:
      CDC Union:
        bMasterInterface        4
        bSlaveInterface         5
The valus before with older Android version were 0 and 1.
Because there is no problem with using this feature with Windows OS I think the
Linux kernel module should also support an interface numbering not starting
with 0.

Reproducible: Always

Steps to Reproduce:
1. Connect SGS via USB to Linux computer
2. Select USB tethering in SGS network menu
3. Linux tries loads correct kernel module and logs "bad CDC descriptors"
Actual Results:  
tethering (Using phone via USB as ethernet interface) does not work

Expected Results:  
ethernet interface should be setup and configured via dhcp

This is a vanilla kernel bug of the cdc_ether driver module.
Please put this information to the responsible maintainers to get it fixed.
