HSP is not a modem manufacturer, it's a term meaning H
rocessing. 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.
