Sc create, devcon install Difference

In Window Driver, There are the pnp(plug-and-play) type drivers, and the non-pnp type drivers. When non-pnp type drivers have once installed, they would be supposed to be used continuously without uninstall. On the other hand, pnp drivers are namely for easy plug-in(out). For two different types of driver, two-ways of installing exists.

1. PNP Driver

sc create [service name] binpath=[c:\...] type=[kernel]

sc start [service name]

sc stop [service name]

Because sc command is used for creating wide-range window-services, this is Not used only for the device driver. But this is also useful for the device driver.

2. Non PNP Driver

devcon install [filename.inf] [hardware id]

Devcon command would be failed if you didn't match the hardwareID in inf-file and hardwareID in argument.

When Devcon install command failed on VM

I was missing two basic points for installing driver on virtualbox because I never experienced developing driver before.

1. Test-certificate driver could only be installed after recovery boot. ( on 32bit window it could be simple, see this )

Settings -> Update & Security -> Recovery tab -> Restart now -> Trouble Shoot ->
Advanced Options -> Startup Settings -> Restart -> F7

2. In INF file, hardware id place should be specified with real device id.

Red-marked place should be replaced with real hardware id. it can be checked in device manager.
