i'm using dual HW 4.12 with FW 3.26, i have no access to the slave vesc when the usb cable is connected to the master vesc.
after clicking the CAN button in vesc-tool and clicking "connect" i get this error message:
"Could not read firmware version. Make sure that selected port really belongs to the VESC.
I don't know if this is a bug of vesc-tool or if i'm doing something wrong.
