Hi Georg,
Sorry - seems like the device was incorrectly connected or my USB
stack got stuck somehow as after a system reboot things started
working:
sigrok-cli --driver=korad-kaxxxxp:conn=/dev/ttyACM0 --show
Driver functions:
Power supply
Scan options:
conn
serialcomm
force_detect
korad-kaxxxxp:conn=/dev/ttyACM0 - Tenma 72-2540 [S/N: xxxxxx] with 2
channels: V I
Supported configuration options:
conn: /dev/ttyACM2 (current)
continuous: on, off
limit_samples: 0 (current)
limit_time: 0 (current)
voltage: 0.000000 (current)
voltage_target: 0.000000, 31.000000, 0.010000
current: 0.000000 (current)
current_limit: 0.000000, 5.100000, 0.001000

Thanks!
Chris
