How to continue using U disk after you stop using U disk

The process of using U disk, if you "safely remove the hardware" after not the U disk pull down, suddenly remembered to continue to use the U disk, what will you do? Generally, it is unplugged. Is there a simpler way?

Using DevCon combined with batch processing, the above complex operation can be achieved by a click. As for DevCon, Microsoft says:

The DevCon utility is a command-line utility that can override Device Manager. With DevCon, you can enable, disable, restart, update, delete, and query individual devices or a set of devices. DevCon also provides information that is relevant to driver developers but cannot be seen in Device Manager. You can use DevCon for Microsoft Windows 2000, Windows XP, and Windows Server 2003.

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

Create a new text file, enter the following code, change the extension to bat at save time, and place 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 to implement the disable USB device and then enable. The long list of things you need to modify, by right-clicking on the "USB Root Hub" and selecting "Properties", then "details" and substituting "device instance ID" to replace the one in the above code. The final note is, "@" and double quotes, this is the key to success or failure!

Another: "Device instance ID" can use the wildcard "*", which represents any character. For example, you write a devcon disable @ "usb*", all USB devices (such as USB keyboard, mouse, etc.) will be disabled.

Well, later encountered in the first paragraph of the situation, just click on batch processing will be able to restart the U disk, you can directly unplug the U disk.
