title: Nexus (10): how to reset/debug usb when not recognized by windows or mac anymore
body: <p>I was happily developing my Android app and debugging it on my Nexus 10 the other day. Next morning the Nexus 10 wasn't recognized anymore.</p>
  
  <p>It shows its charging but no info about USB-Debugging or Connected as Media Device in the upper left corner.</p>
  
  <p>I tried different PCs, Macs, USB-Cables, uninstalled the Nexus 10 driver, did a system cache wipe on the Nexus 10 (in recovery boot).
  A fresh Win7 PC (never seen a Nexus 10) doesn't even try to find a driver for it.</p>
  
  <p>I tried to connect (with the same cable and PCs/Macs) a Galaxy S4 and everything (media device, usb debugging) works perfect.</p>
  
  <p>Of course I tried to enable/disable (USB) Debugging and all the storage variants (MTP and PTP) the Nexus 10 offers. Nothing on the PC/Mac side happens.</p>
  
  <p>Is there a way to debug or log somehow into a file what the Nexus 10 is doing when I connect the USB cable? Can I write a simple app which debugs/listen to what happens on the USB port?</p>
  
  <p>Thanks
  Soko</p>
