pretty sure its the VKtech saleae clone, even if the crystal is mounted on the bottom of the PCB... however it works quite ok now, quess it was problems "tunneling" the USB device through windows to the debian VM
with the native windows application it works just fine, even if sometime it does not acquire enough data really like pulseview, very mighty tool! just today I read about someone exporting CSV from their fullgrown Osciloscope and feeding it to pulseview for comfortable stream decoding and debugging :) > Gesendet: Montag, 14.
