PSLab v5: Device does not finish boot while PV1 or PV2 is connected to VOL #142

My PSLab v5 does not boot properly as long as either pin PV1 (Voltage 1) or pin PV2 (Voltage 2) is connected to pin VOL (Voltmeter). The green SYSTEM LED does not light up. The computer recognizes the device, but it is not possible to open a connection, e.g. via the Python library ("Device not found.")

Booting the device finishes as soon the connection is removed (no power cycle required). The SYSTEM LED lights up and it is possible to connect to the device.

I am not sure if it is a firmware issue or hardware issue.

This issue is still present in the V6. I suspect it's hardware related, but I'm not sure what the exact cause it.
