I have a Discovery 3 connected to a Raspberry Pi Zero 2W with a USB-C to micro USB adapter. The Discovery is recognized, but when I open an instrument I get a "The device has stopped working due to overcurrent" error. Checking the "Disable current limit" box has no effect. I have connected an external 5V supply to the discovery and still get the same error. Other things of note:
1. Connecting the Discovery to a computer with a USB-C to type A adapter causes it not to work at all. I did not see anything about that as being a problem.
2. If I connect the Discovery to external 5V while it is connected to the Pi via USB, it draws no current through the 5V supply. Disconnecting the USB and reconnecting it causes the Discovery to draw about 600 mA through the 5V supply. Is this intentional?
Any help on the overcurrent error and how to fix it is appreciated.
