BQ27621EVM detection.

Other Parts Discussed in Thread: EV2400, BQ27621-G1

We're doing some test and evaluation with the BQ27621EVM-G1 using Windows10 and EV2400.

For the past two days everything was going fine and communication has been working. 

At end of day the EVM was all of a sudden not detected by PC.

We've reboot PC, checked all connections, measured Vdd and checked battery connections but the EVM is no longer detected.

Has anyone run into this kind of thing? 

In the meantime we are still able to use the same EV2400 to communicate with BQ25898EVM.

Any suggestions?
