did you recycle the power on the ez-b?

I did. I get:

Attempting connection to COM3 Comm Err: The operation has timed out. BbytesToExpect: 1

Received: Disconnected Connection Failed: System.Exception: Controller Not Responding at EZ_B.EZB.Connect(String portName) Disconnected

Does the Upgrade run at a different baud rate. i have it set to the default of 9600.

when you power the ez-b, does the led pulse?

Red one Pulses Fast. Blue One pulses very slow.

When I run Diag I get:

EZB 0: Attempting connection to COM3 Comm Err: The operation has timed out. BbytesToExpect: 1

Received: Disconnected Connection Failed: System.Exception: Controller Not Responding at EZ_B.EZB.Connect(String portName) Disconnected

EZB 1: EZB 2: EZB 3: EZB 4:

There's no reason it shouldn't connect - that code doesn't ever change. Try rebooting your computer and cycling the power of the ez-b. Something is confused and needs a restart.

Will do. I Verified the firmware image and it said OK.

Hi, I have connecting problems too. I updated, all went fine. it said to reboot the EZ-B, which i did. When i turn the leds lights up for a while and then starts pulsing. I start up ARC and connecting to EZ-B on both a new project screen and also after loading my projects, it simply tells that it could not connect, wether or i would like to view the connection tutorial.

*Edit I have rebooted system too and it doesnt connect

does the red led flicker at all during a connection attempt?

try connecting from a new project, with no controls.
