Just the one that has been left without support for windows 8, 8.1 and 10 in the latest versions of the driver. This code identifies the revision of the chip and the last letter, A in this case, indicates that it is the Chip PL-2303HXA.

In the chip itself, after that inscription appears another one of the following style LFXXXXXA, where the X are numbers from 0 to 9. As the inscription of the chip is PL-2303HX now had to know if it is the HXA (without support) or the version HXD (new version that does have support). What comes to say more or less they are no longer manufactured and have been left to give support in the latest driver versions. They indicate that it works for PL2303 HXA, XA, HXD, EA, RA, SA, TA and TB chips, with the important caveat that it does not work for Windows 8, 8.1 and 10 for the PL-2303HXA and PL-2303X versions that are EOL (End Of Life). After dismounting one of them and see the inscription PL-2303HX on the serial communication chip, I went to the manufacturer's page where I found the following driver information for this chip. The first thing would be to find out what chip for the USB communication had built-in these ELM327 USB. After searching for information on the internet about it and reading lots of tips indicating downloading the latest version (without result), disabling some specific devices in the device manager (without result) and the like, I came to the conclusion that I had to start from the beginning. After testing every one on the computers with Windows 7 installed and checking that they all worked perfectly I came to the conclusion that it was due to a compatibility problem with the operating system. Immediately tested the same devices on the other computer with Windows 10, with the same result.
