Such a question is too vague.
You should better detail your scenario.

You need a device driver for that device.
If you don't have one (device is developed by you / your company), you have to write one. Alternatively you can use a generic device driver (storage, keyboard) but the device must announce itself as such.

When answering a question please:

Read the question carefully.
Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.
Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question.

This depends on the device and Jochen is correct by pointing to a driver. Contact the vendor of the device.

When it is an USB device the article How to Access a USB Device by Using WinUSB Functions could give some insights.

For a more general approach you should search in the Windows hardware development samples for some example code.
