Hl 340 Usb Serial Driver

08.12.2020by admin

The UC232A USB-to-RS232 serial port converter is the ideal accessory for laptop and desktop computers that do not have a COM or DB9 serial port. Just for web preservation and search engine helps. This is the driver for the oh-so-sought-after Dynex USB to Serial adapter. Dynex are a bunch of assholes and haven’t published the driver – or the fact that it uses the HL-340 controller (not the Prolific 2303 one).

I have Kubuntu 14.10 development workstation and recently I have bought a QinHeng Electronics HL-340 USB-Serial adapter. HL-340 is USB<---->Serial adapter and it is recognised by my kernel:

I am trying to initiate communication via this adapter with Raspberry Pi B+ board, but I am constantly failing.

Whatever text I send to the Raspberry Pi B+ via minicom, the traffic on the line is dead, I've checked with scope. I've double checked the Raspberry Pi B+ setup, the wirings (triple checked with multimeter), the scope wirings and the serial communication is dead. The port on Raspberry Pi B+ is working, because I've hooked up scope on transmit pin of serial port (on Raspberry Pi B+ side) and if I send text from Raspberry Pi B+ (via minicom under ssh tunnel), I get activity on the scope.

I cannot get data from PC via USB serial dongle. How do I test if the dongle works?

Is the adapter loading the right kernel module? I've heard that your device may be CH341 compatible:

lsusb lists the device here as

It is often shipped together with the sds011 sensor. The required kernel module is called ch341 and built with the following .config entry:

If you use make nconfig or make menuconfig you will find this module in

I had to set the communication parameters manually to 9600 baud, 8N1 before I could use the device properly:
