On checking online, I found out that this file should be around the 38 KB mark. This in no was detracts from the usefulness of CCleaner as registry mods need special care anyway! This file WAS there but the size was just 18 KB. While using CCleaner to clean the registry, this had also modified the wpdusb.sys file (one of the default drivers provided by Microsoft). After trying n trying I finally found the root of the problem. This meant I couldn't copy/paste data as I could previously. Hi, I had the same problem of my Nexus 7 (2012) suddenly stopping to appear as a disk drive but now as an MTP Device. This worked on my Nexus 5 with Android 5.0 (updated this week) as well as my old 4.4 Android. Of course - you can also just install the android studio SDK and install all the packages for usb drivers. it will force it to look for a new driver. big thing - DELETE the acer ADB driver when uninstalling. after it is done - select the acer ADB device, right click it, select UNINSTALL then *** this is key *** when uninstalling CHECK THE DELETE DRIVER check box also!ģ) When its done uninstalling and deleting the Acer ADB driver - if it doesn't automatically just start working - unplug the phone and plug it back in - it will usually 99% of the time - just pick up the newly detected usb device and find it as a Nexus and download the appropriate driver really quick and whammo - open up the file manager or whatever default you setup. it might temporarily recognize Nexus 5 and have a ! yellow warning on it until it installs the device driver and it incorrectly identifies as an ACER ADB device. move on.Ģ) In device manager on Windows (I have win 7) - choose the Acer ADB device. Let you computer find the ACER ADB again. Goto Settings, Storage, (three dots in top right corner) Options - brings up "USB computer connection" - click that, Disable Camera PTP if it is enabled, ENABLE (check) Media device (MTP) - if it is already, uncheck it then recheck it.
