Replace missing "Standard Modem Driver" in Win 7

[videobruce]

(Please don't shoot me, this wasn't done thru NT Lite, but the problem could possibly apply.)

I need to replace the "Standard Modem Driver" from a RT7Lite modified Win7 O/S without going thru the whole nine yards. This is NOT vendor specific!

The "Modem" group of drivers was intentionally not added (who needs a modem anymore) when compiling a Win 7 Pro O/S hru RT7 Lite that up to this point (5 years later) was not missed. Without completely re-complying a new O/S (which is a huge project), there must be a way to selectively re-add this single item (driver(s) and/or protocol(s).

This without the actual DVD, just the ISO or the separate original files are available.

The reason is for 2 devices that use' USB serial port' communications that apparently need this. No, I'm not making this up, it's a educated guess after long troubleshooting the problem.

This thread was missing key details, which I found in your MSFN post USB serial interface driver problem, error message; can't find file

By reading Uniden's driver INF, it requires copying this device driver (mdmcpq). You can use the hard-to-see search box on the top of Components tab to find which driver class it belongs. The driver certificate is dated 2014, but looks valid. I don't have the signing tool to check its validity.

Look for a folder named Windows\system32\DriverStore\FileRepository\mdmcpq.inf_amd64_neutral_3f60a6f21f7bb0d9 on your machine.



Remote Assistance & RDC are red herrings. They work on the UDP & TCP network layer, and don't care about drivers except for display acceleration.
