In my case, I have an XP machine here with a working driver if I want to do any PIC programming, but it sounds like you might be up the creek without a paddle. If I run the PL2303 "checkChipVersion_v1006.exe" app, it says "OPEN COM PORT FAILED". If you try to update the driver, Windows says that the best driver for the device is installed, (but it doesn't work!). Like you, the device shows in "Device Manager" with a yellow exclamation mark, and in "Properties" it says:-Ī device which does not exist was specified. VID_067B&PID_2304 for "Prolific USB-to-Serial Comm Port" (PL2303TB chip) VID_067B&PID_2303 for "Prolific USB-to-Serial Comm Port" Windows 8 is supported only in following chip versions:.Windows 8 is NOT supported in HXA/XA chip versions (will show yellow mark Error Code 10).Supports the following Windows OS Family: PL-2303 Windows Driver Installer v1.8.0 or above Device using PL2303HX/X/EA/RA/SA/TA/TB version chips (I've had the board for about 4 years.)įrom the "PL-2303 CheckChipVersion Tool Program v1.0.0.6" readme file:. My chip is labelled "PL2303HX", and is a number of years old. Windows 8 (and, I assume, Windows 10) are not supported in the earlier versions of the PL2303 chip. Just google CH340 drivers and you will find plenty of direct I just downloaded the latest Prolific PL2303 Drivers to try to get my K150 PIC programmer working with Windows 10. I got my usb programmers from Ebay and have had no issues apart from having to install the drivers for one of them. Posted my connections to a pro mini (chinese) in case they are of any use. If it works on win 7 can you post a pic of the com port selections from device manager ? The IDE you are using is not the most stable have you tried 1.6.5 r5 or 1.6.9 ?ĭid you double check the RX TX connections as they often need to be reversed ?Ĭan you maybe supply a picture of the wiring to the pro mini and from the ft232 (or whatever device you are using) ?Īre you connecting directly to the computer (do not use unpowered USB hubs) ? If you have anything connected then maybe take it off and can you try without anything connected ? What are you using to upload (close up picture would be great) ?ĭo you have anything else connected to the board ? We can see you are trying to set up a pro mini using IDE 1.6.7 and you have no port selection and that's it.įirst off is it a cheap copy or a real Arduino ?
The pictures only tell a tiny part of the story.Īnd without any real information it is like trying to win the lottery to get you the answer you seek.
