[Bug 446146] Re: Several Huawei USB dongle don't work with kernel 2.6.31-12.40 (2.6.31.1 update related)

[Andrew Stevens]

Confirm: stock kernel 2.6.31-16.53 does not fix the issue for (my)
Huawei E270.

A custom kernel that includes the patch

diff --git a/drivers/usb/storage/initializers.c b/drivers/usb/storage/initializers.c
index 105d900..ec17c96 100644
--- a/drivers/usb/storage/initializers.c

        US_DEBUGP("Huawei mode set result is %d\n", result);
-       return 0;
+       return (result ? 0 : -ENODEV);
 }

which differentiated the 'apw10' test kernel from 'apw5 works correctly.

Needless to say I'm holding on to that patch like grim death ;-)
