The term stands for Host Signal Processing . Unlike traditional, fully hardware-managed sound or modem cards that featured dedicated onboard processors, HSP devices offloaded the vast majority of their computational work directly to the computer’s central processing unit (CPU).

Avoid generic "driver update" utilities or suspicious EXE files from ad-filled download sites. Many "HSP56 drivers" circulating on the web are actually malware or unrelated modem drivers.
If you have downloaded the driver files (often as a .zip or .inf file), follow these steps:
