How to quickly re-enable a USB flash drive

When using a USB flash drive, when you click on the "Safe removal of hardware" and did not unplug the USB flash drive, and suddenly want to continue to use the U disk, how to do? I believe you must first unplug and then reinsert the USB stick. Here's a quick trick to re-enable your USB drive.

With DevCon combined with batch processing, the above complex operations can be achieved with a click.

The DevCon utility is a command-line utility that can replace Device Manager. With DevCon, you can enable, disable, restart, update, delete, and query a single device or a group of devices. DevCon also provides information that is relevant to driver developers, but not visible in Device Manager. You can use DevCon for Microsoft Windows 2000, Windows XP, and Windows Server 2003.

Note: The Devcon.exe that comes down is a zip tarball that must be decompressed (available winrar). After decompression there are two folders, I386 in the Devcon.exe is 32-bit machine use, and Ia64 in the 64-bit machine used.

Create a new text file, enter the following code, save the extension to bat, and put it in the same directory as Devcon.exe

@echo off

devcon disable @ "usbroot_hub204&1a2797b1&2"

DevCon enable @ "Usbroot_hub204&1a2797b1&2"

Note: The above code is the first implementation of deactivating USB devices and then enable. After that long list of things you need to modify, by right-clicking on the "USB Root Hub" Select "Properties", and then select "Details", with "Device example ID" replace the above code. The last thing to note is, "@" and double quotes, which is the key to success or failure!
