Tips for Coding in Driverland

Try the Mouse Driver First

Sending data the mouse driver is easier than sending it to the joystick driver, and way easier than sending it to the keyboard driver. Once you have it working with the mouse driver, you will understand the basics of working with the drivers. So start with the mouse.

Use the Keyboard Driver Ping and Timeout Features

It is possible to send a key-down command to the driver, then not send the corresponding key-up command (due to a crash or maybe forgot). This leaves the key in a pressed state and acts like you are physically pressing the key on the real keyboard. The keyboard driver has special feature which requires that you ping it every so often (every 100 ms is good) and if the driver has not received a ping in the timeout value (5000 ms is good), the driver will automatically release all the keys.

If you are using the keyboard driver, you will appreciate this feature. Without this feature, you would be rebooting. Often.

Use the SDK utils during development

When you are coding for sending data to a driver, use the SDK’s keyboard and joystick reader utilities to see if the data is being sent correctly to the driver. This way you are sure it is being read correctly from the driver, so you can concentrate of the sending to the driver.

Find the drivers in Windows Device Manager

Just set the View menu to Devices by connection and that makes it easier to see the drivers listed.

Get to know the driver installation log

There is a C:\Windows\INF\setupapi.dev.log file that records all driver install and uninstall activity. Any error’s will be listed in the log with a !!! prefix. This log can get quite large, but you can delete it so that it is recreated when you install the drivers. There’s a lot of fascinating driver info in this log. If a driver didn’t install, this should be your first stop.

Here’s the log entries for running install.bat in the Joystick driver folder. There are no errors during the installation:
