Dear all, I am trying to read out a Unitrend UT71E on OSX 10.10. I followed installation instructions for the unstable (Pulsview) distribution.
When I try to read out the UT71E (switched to send via its button) I get /* sigrok-cli --driver uni-t-ut71e:conn=1a86.e008 --show Driver functions: Multimeter Continuous sampling Sample limit Time limit Scan options: conn uni-t-ut71e - UNI-T UT71E with 1 channel: P1 Supported configuration options: (null): continuous: limit_samples: limit_time: */ and /* sigrok-cli --driver uni-t-ut71e:conn=1a86.e008 --scan The following devices were found: uni-t-ut71e - UNI-T UT71E with 1 channel: P1 */ but reading out results in an error /* sigrok-cli --driver uni-t-ut71e:conn=1a86.e008 --samples 1 -l 5 sr: libsigrok loglevel set to 5. sr: backend: Sanity-checking all drivers. sr: backend: Sanity-checking all input modules. sr: backend: Sanity-checking all output modules. srd: libsigrokdecode loglevel set to 5. sr: hwdriver: Initializing driver 'uni-t-ut71e'. sr: usb: Trying to find USB device with VID:PID = 1a86:e008. sr: usb: Found USB device (VID:PID = 1a86:e008, bus.address = 20.9). sr: usb: Found 1 device(s). sr: hwdriver: Scan of 'uni-t-ut71e' found 1 devices. sr: usb: Trying to open USB device 20.9. sr: usb: Opened USB device (VID:PID = 1a86:e008, bus.address = 20.9). sr: hwdriver: sr_config_set(): key 50001 (limit_samples) sdi 0x7f8250c1d1a0 cg NULL sr: uni-t-dmm: Setting sample limit to 1. sr: session: Starting. sr: std: uni-t-dmm: Starting acquisition. sr: std: uni-t-dmm: Sending SR_DF_HEADER packet. sr: session: bus: Received SR_DF_HEADER packet. cli: Received SR_DF_HEADER. sr: session: Running. sr: uni-t-dmm: No need to detach a kernel driver. sr: uni-t-dmm: Failed to claim interface 0: LIBUSB_ERROR_ACCESS. sr: uni-t-dmm: HID chip init failed: -1. */ Any help is appreciated Norbert Danneberg
