Bug Fixes
- Keysight E36313A USB PID — corrected the USB product ID for the Keysight E36313A power supply (
2a8d:1202) in theSUPPORTED_USBtables used by the box’s USB scanner and the CLI’squery_instrumentspath. The PID was previously a placeholder (????), so the instrument was not recognized on plug-in. A matching udev rule was added so PyVISA can open the device directly via libusb (MODE=0666, with theusbtmcdriver unbound onbindto prevent “Resource busy” errors).
