I have installed the 30P firmware yesterday. After that I cannot connect my phone with the PC using USB cable. When I plug in the phone, the computer gives following error:
"Windows found driver software for your device but encountered an error while attempting to install it.
MOTOROLA_NA USB LAN LINK
A service installation section in this INF is invalid."
