There may be some cases where the packages don’t work for your particular device. Other times it’s necessary to install the specific driver for the Android device. For both cases on the page resulting from the selection of your brand in the dropdown of this page you will find different specific links to get your required Android USB drivers.
IMPORTANT. Read before updating the drivers of our device.
Before carrying out any update of the drivers of your Android phone or tablet it is recommended that you uninstall the drivers that were previously (remember that only connect your device once some drivers are installed) and then install the new ones, so Generally this is not necessary, but there has been some case in which conflicts between both controllers were created, producing errors when recognizing the device or partially limiting the functionality of the new drivers.
