The USB to RS232 conversion cable makes it easy to connect USB and serial devices, allowing the serial devices to have plug-and-play, hot-plugging and other functions.remove the 5.4 line kernel which seems some kind of forward port from 18.04?! and switch to 4.15.0 / linux-generic.I do know that my board uses a CH340 USB driver. Description USB To RS232 DB9 Serial Port Converter Cable is an 80 cm cable with two heads of a 9 pin male DB9 connector and a USB v2. $ find /lib/modules/$( uname -r ) | grep usb/serial I’m not sure exactly what the problem is but I have installed the Arduino IDE on my Jetson Nano but I can’t upload any programs to the board, or use the serial monitor. I just tried this and it worked but make sure you restart computer. Pretty much all of them do, but seems there was this one that was wrongly packaged and of course released without checking. Prolific usb to rs232) 2) Right click on the setup and choose troubleshoot compatibility or run it as a program that is compatible for earlier version of windows. Those cannot be used due to a different module format. They are also in linux-modules-5.4.0-99-lowlatency. Recently I got a ESS32-CAM card and it contains the same Ch340 chip and it has worked fine even with the USB cable so I suspect that the ch340 designer released an updated design of the chip that meets the USB timing specs or maybe some aspects of the board design are adjusted to help make the timings.īottom line, unless you enjoy chasing down problems you will be better off buying the more expensive ftdi or other non-Chinese designed chips.The 5.4.0-99-generic modules package had no usb serial drivers, while 4.15.0-96-generic did. How Configure HL-340 USB-Serial adapter 1 download zip file of above adapter driver for Linux 2 extract it 3 run make command 4 connect USB serial adapter. When I say I get it to work, all I have been able to do is install the wrap connector and get the adapter to talk to itself as verified with putty. This would also explain why sometimes it will work after installing into a different USB connector on the PC since those timings can vary as well. Consequently if a chip designer is not careful about meeting USB timing specs then there will be situations when that chip will not work. From my work experience I know that the USB timings are very critical in order to maximize performance. However, if I use an extension USB cable most of the time it fails to work. I say this because I have noticed that if I plug my Ch340 board directly into my USB port it works. Next, it is apparent that the Ch340 design does not meet USB standards in the area of critical timings. After doing that I was able to solve the install failed problem. So if anyone has an idea what to do or where to find the right drivers for windows 7 64-bit, please help me. First thing to do is run/click the uninstall button. Hello, i just bought an adapter USB to serial (HL-340 or RS232), but the drivers that came with it work only for 32bit. I have Kubuntu 14.10 development workstation and recently I have bought a QinHeng Electronics HL-340 USB-Serial adapter. ![]() Since my last posting I have discovered some things that may help eliminate this problem.
