Sony Ericsson Xperia X10 USB Debugging Detection Issues My PC - well, specifically, Flashtool - doesn't detect that my X10 has USB Debugging turned on, even though it displays that it has been activated both in the Settings menu and the notification shade. I've tried the modded Flashtool from XDA-Dev, and the latest versions, but to no avail. Any suggestions? I believe the drivers are up to date, as I can turn storage mode on when plugging it in and transfer files just fine. Rooted, running stock. It was fine pre-root, but as soon as I rooted it the first time around, it hasn't been able to detect. Recovery can't be flashed due to the lack of debugging.
Install Sony Pc companion.Go to folder in which flashtool is installed mostly C:/Flashtool.You will find Drivers folder in which you will find Driver.exe click it select the driver for your device click install.

Windows will give you error select Trust the vendor. It is better to turn off your antivirus. 

Once installed enable usb debugging mode and connect
