Another was from Sewell where I downloaded the file "SW-1301_v1.2.1.zip" which when unzipped had the following executable inside: "PL2303_Prolific_DriverInstaller_v1210.exe," apparently from Prolific Semiconductor.Īlso, I am curious if some of the manufacturer drivers aren't really just. One of those converters that required a manufacturer driver was the Targus PA088. This definitely occurred on XP and I am pretty sure it occurred on Windows 7 as well. However, I have used some USB to RS-232 converters in the past that required me to download the driver from the manufacturer.

I understand that there is a Windows class driver for USB-232 interfaces, usbser.sys, that conforms to the CDC specification. As I said, it is just that this has been a point of curiosity for me for a long time. Also, my question really applies to Windows and the driver, not an embedded application. However, I am not currently working on a USB project. I found this forum and it looks like exactly the place to have it solved.


I have a point of curiosity that has annoyed me for a long time.
