I tried the older driver available here:http://www.prolific.com.tw/US/ShowProduct.aspx?p_id=223&pcid=126And this seemed to work for Windows 11. Weird that an old driver works better than the latest one.I have the PL-2303 TA chipset. Answer from ejohanson on techcommunity.microsoft.com

October 13, 2021Issues with rs232 serial to USB driver on Windows 11
Best option is to roll back to win10. Win11 has too much issues with serial or rs232 drivers. As a network engineer i have to console eah day. So we have two types...prolific and ch340. Win10 works fine with the built in ch340 chipset and can console to every switch/router. Prolific works if you manually install the latest driver. But in win11 i had endless issues with both chipsets..even if they say win11 compatible. More on reddit.com

r/Baofeng on Reddit: Windows 11 & Prolific USB Drivers
October 13, 2021 -
Recently installed Windows 11 on one of my laptops and my programming cable stopped working after a security update (which was odd because it worked fine with Win11 for a while at first).
Device manager said the Prolific 2303 (2303TA in my case) wasn't supported by Windows 11 at all, but I found a workaround:
-
Download and install the appropriate driver package from https://oemdrivers.com/usb-prolific-usb-to-serial-driver
-
After installing, go to the Device Manager and find the device listed under Ports (COM & LPT).
-
Right click on the Prolific item in the list and click on Properties.
-
Click on Update Driver.
-
Click on Browse my computer for drivers.
-
Click on Let me pick from a list of available drivers.
-
You should see a list with several Prolific driver options. I chose driver version 3.8.25.0 (7/12/2018) and the cable resumed working as expected.
Hopefully the helps someone else in the future!

This is what helped me in my case There is a working driver at http://www.prolific.com.tw/US/ShowProduct.aspx?p_id=225&pcid=41 , a bit down the page listed as "DCHU (for PC Vendors)". Getting it installed is a bit tricky, it seems. What I did is this: First 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. It will add the two driver packages to the driver store and tell you what oemXY.inf files it has assigned to them. Then "pnputil /enum-drivers", and in the output look for Prolific drivers other than the ones from the previous step. I had only one other entry, a "ser2pl.inf" version "09/16/2021 3.8.40.0". Disconnect the device, and "pnputil /delete-driver oemXY.inf" with the INF file you located in the previous step. Connect the device again, and it should work, at least, it does for me. The problem is probably that the non-working driver is the newest (September 2021 vs. July for the ones from the download page) and so Windows prefers it over them.
