You do realize how many changes have gone into the kernel since 2.6.29, right? That's many years and tens of thousands of patches, so if you are stuck with that one, you are really on your own (or you need to push on your vendor to resolve this issue, it's their fault, not ours). If you can duplicate this on .37, we will be glad to help out here. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
