Driver can auto-download via Windows Update (Windows 7, 8, 8. Windows Vista, 7, 8, 8.1 Certified WHQL Driver Compatible with Windows 2000SP4 & Server2003 Installer version & Build date: 1.12.0 () (For PL2303 HXA, XA, HXD, EA, RA, SA, TA, TB versions) This is the Prolific website read on the driver I installed:ĭownload File: PL2303_Prolific_DriverInstaller_v1.12.0.zip July for the ones from the download page) and so Windows prefers it over them. The problem is probably that the non-working driver is the newest (September 2021 vs.

If it does not work then take a look at the Prolific original drivers. The driver has been added below for the Gigaware version of the software. The installation process has been explained here ( FT232R USB UART Driver ). 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. The Gigaware USB to Serial Driver is nothing more than another USB driver from Prolific. 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)".
