USB: ti_usb_3410_5052: adding multitech dialup fax/modem devices
Alex Manoussakis [Thu, 22 Apr 2010 22:18:20 +0000 (15:18 -0700)]
The following patch adds support for Multitech Systems' MT9234MU and
MT9234ZBA usb dialup fax modems. It is based on a patch and firmware
provided to me by Multitech Systems' support, after I reported to them
that my MT9234MU modem was not working with recent linux kernels.
