The problem is probably that the non-working driver is the newest (September 2021 vs. I had only one other entry, a "ser2pl.inf" version " 3.8.40.0".ĭisconnect the device, and "pnputil /delete-driver oemXY.inf" with the INF file you located in the previous step.Ĭonnect the device again, and it should work, at least, it does for me.
Then "pnputil /enum-drivers", and in the output look for Prolific drivers other than the ones from the previous step. It will add the two driver packages to the driver store and tell you what oemXY.inf files it has assigned to them.
What I did is this:įirst install the downloaded driver by unpacking the zip file and "pnputil /add-driver *.inf /subdirs /install" (the /install is probably not necessary) from the extracted "Win11_DCHU" directory. Getting it installed is a bit tricky, it seems. There is a working driver at, a bit down the page listed as "DCHU (for PC Vendors)".
