Hi is there any way to use owondump with an Owon VDS1022 osciloscope? I'm, using libusb-0.1-4:amd64 on Debian 9

in lsusb it shows as: Bus 004 Device 002: ID 5345:1234 Owon PDS6062T Oscilloscope

but if I try to connect with owondump is says: ./owondump ..Found an Owon device 5345:1234 on bus 004 ..Failed to claim interface 0: -9 : 'Bad file descriptor'

did you have any clue? thanks!

I think the VDS1022 is an entirely different device that happens to reuse the PDS6062T USB IDs; owondump is retrieving a snapshot of the 'scope data but the VDS1022 looks like it needs something doing realtime capture.

Is it possible to continously(!) capture all measurement data from owon oscilloscopes? Such as an audio signal is catpured with the scope through it's A/D converter and the data in turn is send via USB to the PC (for D/A conversion or otherwise processing/analyzing a continous signal). The API documentation and sources are simply not clear on this issue if this is possible in principle with Owon (SDS1102) scopes, or if only signal snapshots can be captured which is useless for my desired use case. I would implement continous data capture myself and provide the feature but won't buy a scope in question if continous capture is not possible.
