USB issues with 3.1.2
Posted: Mon Aug 13, 2012 5:42 am
I just upgraded my softare to 3.1.2. and I'm having major USB connection issues. As soon as I plug in the USB cable with the ignition on, the Windows hourglass/spinning symbol comes up and never goes away. The program starts to run sluggish somewhat and I cannot upload a calibration to the ECU without it failing. I tried the "Test USB function", but that fails every single time with an error. Kmanager can read the ECU and is returning data in the Kpro tab, and it does say "Driver Installed" in the bottom left corner. Here is what I have tried so far:
- Two different laptops. One laptop is an Asus has dual boots of Win 7 and Win 8 on it. Also tried a Mac running Win 7 in Boot Camp. All three builds exhibit the exact same behavior
- Tried completely uninstalling the Kpro drivers in the Device Manager. Was able to get Kmanager to NOT connect to the ECU when plugging in the USB, but "Drivers Installed" always showed displayed
- Tried all the USB ports on both computers, same results
My Kpro ver III ECU is running 3.01 firmware. After about an hour of different combinations, I was able to get Kmanager to successfully upload a new calibration by opening Kmanager, loading the new calibration, turning on the ignition, then plugging in the USB cable and immediately hitting upload. Any deviation from that sequence will bring up the spinning hourglass and any attempts to upload will fail, but even executing that sequence has about a 50% failure rate. Sometimes it will look like its uploading then the progress bar will freeze and the frame rate of the animation progress will slow down to almost nonexistant. I have narrowed it down to a USB problem due to Kmanager running 100% fine until the ECU is plugged into it. I did not have this problem with 3.0.3 on either of the laptops with any of the Windows builds. It started when I upgraded to 3.1.2.
I also have no antivirus software on any of the Windows builds.
