The drivers to connect the Huawei Ascend Y511 to a Windows PC are below. These drivers can be used to flash the firmware to a stock ROM removing bloatware and unlocking more potential.
If you connect your Y511 without using the drivers, it will just charge your phone, or it may come up as a mass storage device so you can backup photos etc. So if you only want to do a backup or charge your phone don't install the drivers.
