So you can try to downgrade your Prolific USB to Serial driver. Here’s how you can do it: On your desktop, right-click on the Start button, then select Device Manager. Double-click Ports(COM & LPT), then right-click on your Prolific USB to Serial driver to select Update driver. Click Browse my computer for driver software. For Prolific USB VID_067B&PID_2303 and PID_2304 Only - Includes User Manual, Driver Release Notes, CheckChipVersion Tool, Windows Driver Certification - Installer supports silent install (add '/s' parameter when running program) NOTE: Windows 8/8.1/10 are NOT supported in PL-2303HXA and PL-2303X EOL chip versions. Prolific Technology is a IC design house company and ASIC design service provider for USB Smart I/O (USB to UART, Card Readers, External USB Drive), Intelligent Green Energy Saving, and Mixed-Mode Hall Sensor solutions. 9) At the second Update Driver Software prompt, select “Let me pick from a list of device drivers on my computer” 10) At the third Update Driver Software prompt, scroll down and select “Ports (COM & LPT)”. 11) At the fourth Update Driver Software prompt, select “Prolific USB-to-Serial Comm Port Version: 3.2.0.0 [7/31/2007]”.

I've got 3 prolifics (those blue dongles, PL2303TA inside) and had problems even with Win7. After messing with several drivers in past it works now (I think the latest driver has been installed automatically, but not sure). Not with all three, one disconnects after some time (~hour). People say the Win7 and 10 recognize a fake PL2303 and do not allow to install it, or, it switch them off after a while. There is only one or two chips supported with Win10, afaik.

Btw, this is the driver in my Win7 which works nice. LOL, fake PL2303 chips as well now. I womder how cheap a product has to be, so that its not worth cloning.

Usb To Serial Driver For Windows 10

On a vaguely related note. There are STM32f103 boards that emulate the CH340g USB to Serial adaptors.

( and also do USB to SPI and USB to I2C) and the firmware binary was posted to another thread. But the cost of those is about 5 x as much as a CH340g adaptor. The main problem is of course Windows, which does not provide a easy way to load the built in USB to Serial device driver which has been part of Windows for many years.

A few years ago I purchased 10 x USB-RS232 Prolific IC serial cables to supply with a product I was selling. All these had problems under Linux (Windows?) where they just stop working and the you have to reset them. On further investigation they don't even use RS232 level signals and only TTL but with the correct logic.

I managed to have eBay refund me for all 10 pieces. Still have them, might be useful for the cables one-day.

Prolific Usb To Serial Driver Windows 10 Fix

A couple of year back I purchased two USB PL2303HX to TTL converters. These work well. I wanted to get an extra couple but these had similar issue like above. Looking at the IC it has no markings on it. Again refunded in full by the seller after I complained. So I tried another eBay seller. I made sure the listing image showed the Prolific logo and type on the IC and went ahead and ordered another two.

You guessed it, no marking on the IC and not working reliably. Bus and cable car simulator save game download. Seller mucking me about (only wanted to refund half!) so I lodged a claim. Seller has now agreed to refund in full and I will then close the case. I've now ordered 3 x of the CH340 variety so will see how I go with those. I don't have issues with them on the UNO copies. It's a pity about the Prolific parts, years ago they were less likely to be fake but now I won't bother with them any more.
