Hello,
I am on Ubuntu 22.04.3 LTS and I have compiled and installed all sigrok
components as described here: https://sigrok.org/wiki/Linux
I have a UNI-T UT61E device and have two cables to connect to it, the
RS232 UT-D02 cable and the UT-D09 USB/HID cable with the CP2110 HID UART
Bridge.
The UT-D02 calbe works: sigrok-cli --driver
uni-t-ut61e-ser:conn=/dev/ttyUSB0 -O analog --samples 5
But I can’t get the UT-D09 cable to work, no matter what I do. I tried
the with and without the “-ser” and I tried different connection strings.
Here is the debug output of one such attempt:
-- snip start --
sigrok-cli --driver uni-t-ut61e-ser:conn=hid/cp2110 -O analog --samples

-- snip end --
Here is the output of lsusb:
-- snip start --
Bus 004 Device 006: ID 10c4:ea80 Silicon Labs CP2110 HID UART Bridge
-- snip end --
I also tried the ut61 scribe from the “UT61E not working on Ubuntu
16.04” thread, that basically does a usbreset:
-- snip start --
/usr/bin/usbreset /dev/bus/usb/004/006
No such device found
-- snip end --
Any ideas how I could get it to work? Or at least what further debugging
I could do to get closer to the solution?
Thanks a lot!
Christian
