Reasons Behind Not Recognizing
When you connect USB to your system, you may find the message "device not recognized". The main reason behind this is the presence of corrupted INFCACHE.1 file. This file is hidden and has only restricted access. If this file is deleted then Windows automatically rebuilds the file. So in order to fix the problem you need to delete the corrupted file so that Windows may rebuild the proper INFACHE.1 file.
Methods to Fix
In order to delete the corrupted file you need to have permission to access the file. For that initially you need to open 'Windows Explorer' option under 'Explore' in 'Start' menu. Then in the address bar you need to type "C:windowsinf" and click 'Enter' to access INFACHE.1 file. Now right click on this file and select 'Properties' option. In the 'Security' tab of the corresponding window, you need to click on 'Edit' option to edit permission of the file.
Next you need to add options to user groups. You need to type "Administrators" in the usergroup field and then click 'Ok'. After setting the administrator to 'full control', you need to click 'Ok' in order to delete the file. On deleting the corrupted file, Windows will automatically rebuild the file thereby fixing the problem. And the operating system would start recognizing the USB device.
