HSP is not a modem manufacturer, it's a term meaning
Host
Signal
Processing. A fancy name for a 6 dollar modem that depends on the host cpu to help it along with it's job. While HSP56 MR may be a correct model number, I don't have a clue who built your modem or where to get a driver for it. All I can suggest is to read our
Modem Help Guide and read in an attempt at learning how to properly id your modem and who made it. Else you can use our
Advanced Driver Search wizard to look for drivers posted in our database that match your modem description.
