I have an AVB378PRO that is spiking, I have tried many of the troubleshooting measures found in similar threads in this forum. For instance, I have tried a different pen and also swapped out the powered USB cord that connects the computer to the teacher plate with no effect.
The driver is 5.7.22.1 and the firrmware is 8.07 build 2.
The board is currently connected directly to the computer via the "back-up/testing" USB cord found on the back of the board as I am attempting to see if that corrects the issue and may help identify the cord that connects the teacher plate to the board inside the conduit mounted on the wall as the culprit.
In the meantime I am wondering if anyone can tell me if the firmware needs updating and how to go about accomplishing that.
Thanks in advance.
