Hello. I may have a hardware issue with my Analog Discovery 2. Wondering if anyone can offer any technical support? Worked fine for a couple of years. Recently had it connected to an external 5V,3A external Power Supply which seemingly worked fine for a week or so. Today it will not power on and is not discoverable (according to journalctl) by my Linux OS, with or without the power supply connected in several different USB ports. For troubleshooting I also have a digital discovery which is detected fine on the computer and in waveforms using the same usb cable /port. Is there any board level troubleshooting I can perform? I'm _very_ keen to get this working again.

After a capture, any changes to the logger's channels, formula, time scale deletes all the data. Is there a setting or a way to stop this from happening? Use case: I captured a 12h battery discharge curve. I'd like to switch to 24h time scale and capture a charge curve on the end.
