USBTMC Rigol DS1054 USBTMC doesnt download data from the scope

[VinicioGonzalez]

Using USBTMC with a Rigol DS1054 doesnt download data from the osc. If I connect trough LAN all is working well.

• How to reproduce: Connecting USB to Rigol DS1054

e.g. ngscopeclient scopeUSB:rigol:usbtmc:/dev/usbtmc0

• Issue

ngscope connects to the Rigol, I can manage for example the Y axis but when I acquire data the download always is 0

• I tried different buffer size

e,g. ngscopeclient scopeUSB:rigol:usbtmc:/dev/usbtmc0:2048 etc etc

But no luck.

• Versions

1. OS: Debian 13. Kernel 6.12.42
2. ngscopeclient

ngscopeclient v0.1-30-g47e5ea9e
libscopehal v0.1-14-gbe8bf899
Dear ImGui 1.92.4 WIP

Thank you
