VESC75/300 USB Connection Issue

Good evening,

I am using two VESC 75/300 for an engine test rig.

Unfortunately one out of the two VESC 75/300 can´t be connected by USB to the laptop. I tried a lot of things, different cables and drivers.... makes no difference. The andorid phone app works well with both of them.

Both are release 3 hardware with FW 5.1.

Would be great if someone knows how to sole the USB-issue.

One funny thing is that the one with the USB issue has a mysterious red light near to the on/off switch. Does this mean anything?

Thanks and best regards

I think I had a similar issue. The red light indicated a fault (see manual) . As long as you have the fault you can not connect via USB. In my case it was a ADC Input out of range from start (booting up). Check App Settings-> "Safe start" to be "false", then check if one of your inputs or whatsoever is causing the fault. With terminal you should read the faults of course. When you solved the fault then you can turn on "Safe start" again. Regards Oliver

Hi Oliver!

Thank you!

Maybe we have a misunderstanding regarding the light? I did not mean the red "status light". My "mysterious red light" was this one underneath the cover plate:

I tried more expensive USB data cables (PPM cables disconnected) and now both VESCs can be connected. Next I try to run both VESCs simultaneously (one for motor, one for generator) on 2 VESC tools one one computer. Still some issues with that but will work out. Has someone try this already?

Best regards

Gerhard
