Once USBaspLoader finishes loading the new firmware, it is no longer a "USBaspLoader". Your application code will take care of everything, you can put CDC code into your application code if you wish.

it looks like if you use external interrupts (as in INT0, INT1, etc), the interrupt is generated on a rising edge signal. Pin change interrupts occur regardless of rising or falling edge. This may be one problem.

You are right I think, button 1 should be the usage minimum.

Now I have no idea what's wrong at all.

I'm not sure if you can read data from devices that already have a driver loaded.

Shouldn't the usage minimum for the button be "No Buttons Pressed"?

What does the entire report descriptor look like?

I''m confused. What does this slider do? What software works with it? What are you using to get the readings? Also, why increments of 8191? You seem to want 3 bit resolution, so 8 total positions, which sounds right, so you'd want increments of 1, right? Also try to make sure everything is a whole b...

Where are you using the 1N4148? They are not Zener diodes at all.

control transfer, it's using usbFunctionWrite and usbFunctionRead

don't worry about setup and status stages, setup stage should be already finished in usbFunctionSetup, and status stage is taken care of automatically i think

the device descriptor is generated automatically by v-usb using settings in usbconfig.h

go read the official HID documentation from USB.org 1. Every "main item" in the report should have a usage, it's undefined in this case probably because there's no real set meaning to the data. Go read section 5.5 2. Every report can be either "input", "output", or &quo...

The shear number of things that could be wrong is huge The number of people on this forum is not You definitely did not provide enough details for anybody to help, I myself am not familiar with the PLL clocks of the ATtinys... but double check your clock and compilation settings by running a LED bli...

a stab in the dark, but it looks like you are executing gcc from the mingw's bin directory, did you copy all of libusb's files to the bin directory? if not then that definitely won't work. You need to execute gcc where your project actually is so the header files included by the .c file can be found...
