Recently changed from Win10 to Win7, HP comes with a USB mouse always detected problems, need to manually detect hardware changes to re-use the mouse.

At first, it has been implemented by using the computer-----------------Device Manager------------to detect hardware changes, especially troublesome.

DevCon

This is a command-line tool that Microsoft provides to early system device management, which is equivalent to the command line Device Manager.

Microsoft's official website download connection has broken down ... There are 32-bit and IA64 bits on the internet (basically useless, because the 64 bits of the PC are not IA64 architecture), can be run after downloading

The parameter excerpt is as follows

-R if specified would reboot machine after command was complete, if needed.
<machine> Target machine name.
