How do I change the COM port on my USB to Serial adapter? If the adapter is installed on COM5, a device with such a limitation will not work until the COM port is reassigned to COM1 - COM4. would not work with a USB to Serial adapter when everything appears to have installed fine is that some devices will only scan a limited number of COM ports.įor instance, it is very common for a PDA to have a limitation of scanning the first four (or sometimes two) COM ports. The most common reason that a device such as a PDA, GPS, cell phone, etc. Troubleshooting The driver is installed properly, but the device is not working: If the device is installed properly, you will see 'Prolific USB to Serial Com Port.'.Click on the plus sign (+) next to 'Ports.'.Start -> Control Panel -> Hardware and Sound -> Device Manager.

I already ordered the replacement cable from AliExpress and will update the topic when I'll have something more to report. Even more, I can cut the RJ45 from Exar cable and put RJ11 here, resulting in $5 native RJ11->USB cable. With zero soldering, duct tape and other spaghetti-style connections. I spend $5 on EPSolar cable, RJ11/RJ45 jacks are about $0.05 each, CAT5 is dirt cheap, coupler is about $2, so I got working and stable cable for my KID for less than $10. So now my cable for Midnite KID looks like this:Īnd yes, Exar cable works with Linux default cdc_adm driver perfectly. The cable comes with RJ45 connector on one side and luckily I got RJ45 coupler by the hand: And then I suddenly spotted a data cable for EPSolar Tracer that has Exar USB-SERIAL chip inside. My Linux device was powered from the same Midnite KID, having the same ground already! That means swapping RX and GND just made a short-circuit between data wire and real ground resulting in zero signal! Powering the same Linux PC from external power supply made it work like a charm.Īt this stage my last PL2303 got burned and I looked around for something else. It could be fixed by swapping RX and Ground wires, but. It seems like those cheap PL2303 boards are designed for TTL 3.3v signal levels and while they can handle UART 5v voltage, data becomes inverted. However I was able to see the pattern in that message and it could be possibly decoded. After several liters of coffee I realized that on Mac and Windows I had to revert RX and GND for uknown reason, otherwise message text was garbled. I was shocked and overwhelmed - it works with Mac, works with Windows 8 and 10 PCs, but not on Linux, even with latest kernels and drivers. I spent a day backporting 4.19 driver to old kernel and recompiling, bricked and restored my Linux PC several times and finally got it working, but not with Midnite KID. Previous driver could possibly work with 'cheap UART TTL 2303' converter, but most of the time it refuses to.

To handle HX series there was a patch in pl2303.c driver around kernel 4.2 adding a thing called TYPE_HX mode. There is completely other story with Linux drivers.

It could be easily fixed using old drivers, as with the link above or here:

To cut some tails they managed to change latest Windows drivers rendering them incompatible with fakes. Prolific itself never produced HX chips, only HXD.

So, first of all, there are tons of fake PL2303 chips, most of them are called PL2303HX. Well, sorry for necroposting, but I want to share some interesting information on PL2303 and Midnite devices.
