EV2400: No acknowledge from device (anymore)

Part Number: EV2400
Other Parts Discussed in Thread: BQSTUDIO

Hello,

after working fine previously the EV2400 no longer detects any batteries connected to it (SMB).

The device seems to run fine beause:

- all LEDs are on

- device is recognized by byStudio

What we did so far without success:

- EV2400 firmware has been updated to 0.32

- bqStudio reinstalled

- bqStudio updated to 1.3.104

- checked for unrecognized devices in device manager (there are none)

- tested with different batteries (with different ICs) on different (Win10) PCs

- tried another EV2400 device

- tried different connection cables from EV2400 to battery

Both systems have been working fine before. The only thing I could think of would be a Win10 update messing something up...

Thank you for helping me out.
