Maybe it will be able to help you.

Hi I followed this tutorial: m It is not C# but it gave me good start at understanding how the basic USB works (Control Messages). - See my (Roelf) comment on the third part of this tutorial if you do not understand the direction thing I have started writing my own custom c# class for my own use. I ...

Hi I am referring to the following document: m And the following excerpt: If your application sends notifications only, you don't care whether an unsent notification is lost. In this case you simply call usbFunctionInterrupt() without any checks. Could someone clarify this please. I could not find a...

PS And if for instance I do make a keyboard HID, which VID/PID should then be used?

Since Windows binds the driver by VID/PID, you would bind the HID driver instead of libusb to the IDs. I really don't understand this. I have to...

Ok, from what I can determine, is that I can't make a HID device without a Report. So what I am trying to do now is as described in the wiki: Vendor type requests sent to custom HID class device The advantages of a custom class and a HID device can be (kind of) combined.

Hi

I created a project in AVR Studio and copied the files to the directory and added usbdrv.c and usbdrvasm.S as described in other topics. I also set my frequency in the project settings.

It works, but is much faster than compiled via MingW and the circle is much bigger. Any ideas why?
