Hello,

Does anyone know the best way to write host software to communicate with a USB HID device? I have created a USB HID keyboard and mouse using an Atmega32 microcontroller and it works with my PC, but I would like to be able to receive input from the microcontroller and write to the microcontroller's memory from an application.
 

I have done this 7 years back using VB6. I made a USB camera and connected it to the PC. My host Software was written in VB6. It was a straight forward implementation.

I wonder if Atmel has PC example code with their USB demonstrations. Microchip has e.g. a lot of it. Basically, the access can
be performed at the Windows application level. You utilize setupapi.dll to identify the device and perform device IO to exchange
HID messages.
 

If it works with you PC and it is HID compliant then what is left? If it is USB HID compliant, windows (and Linux) on PC already supports that without any add on.

If you haven't put the HID function class driver in your microcontroller and just interfaced a keypad with that then it makes sense to write something on host side. You can use WinUSB to communicate with your non-standard USB device on windows.
