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
Jonas SteinUSB serial dongle
. How do I test if the dongle works?1,37922 gold badges1414 silver badges4040 bronze badges

Is the adapter loading the right kernel module? I've heard that your device may be CH341 compatible:
scrussscruss
lsusb
lists the device here asIt 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 inI had to set the communication parameters manually to 9600 baud, 8N1 before I could use the device properly:
