Feb 24, 2013 · My developemnet option doesn't work, if I click on it, nothing happens. I tried it with 4.0.4 Stock and MCL, which was installed after a downgrade from 4.1.1. It looks like the device isn't rooted anymore too after I installed the Stock-ROM. So what can I do to get USB-debugging work, if I cannot activate it in the menu.
Look for 'Universal Serial Bus Controllers' and click on it. Out of a number of options, choose USB Root Hub, right click and choose Update driver. Do the same from Generic USB Hub and USB Root Hub (USB 3.0/3.1). Restart your PC and try connecting your Android phone and check if USB debugging is working now.
