I'm trying to connect my Google Nexus 7 to my PC for Android development but so far I've been unsuccessful.
I've tried connecting to my PC using different cables. When I connected the device to my Windows 7 PC, I didn't get any notification on Android or my PC that a device was connected. In "Other devices" my PC shows an Unknown device. I tried using MTP and PTP, as well as disabling and enabling USB debugging. I've used Nexus Root Toolkit, Universal Naked Driver, Nexus 7 toolkit, and I've tried this tutorial and many others and nothing has helped me.
I don't understand why there aren't any notifications on Android. Could it be a hardware problem? How can I check it?
