Ick, really old obsolete kernels like that one are not good for trying to run new hardware with. I suggest contacting the company that is forcing you to stick with that version, and getting support from them to do the needed backporting of this driver. > So probably the best is to try back-porting the ZTE usb-serial > driver...

You can try to backport it, it shouldn't be that hard, but your really going to be on your own here, sorry. best of luck, greg k-h
