Google Nexus 7 not recognized via USB 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?
Make sure that:


Your device is in USB Debugging mode
You have the device drivers installed
With the device connected, delete any 'Android' devices in the device manager. Do this by highlighting it and pressing the delete key.
Disconnect then connect the device.
