USB Disconnecting from MS3
I finally got my car running today, and the main problem I have been having so far is the USB communication dropping out while tuning. The most common situation is that about 20-30 minutes after connecting, the laptop will lose connection to the MS3X and Tuner Studio will say it is offline. After this, the only way to reconnect is to restart the laptop.
Additionally, a couple times today the laptop blue screened right as I plugged the cable in or told Tuner Studio to start VE tuning.
Any ideas of what's going wrong? It seems like some driver for the port communication is dying and sometimes taking Windows with it, but I'm not sure how to find out or fix it. Window's device manager says the port is working correctly after the disconnect, but neither Windows nor Tuner Studio recognize the cable being plugged back in after it happens.
