Do someone have an example, how to implement this ? I was searching the half day, but I cant see where to start. Is this done with another report descriptor or is there more ? Until now this is my (not all, borrowed some) code: ... stuff char usbHidReportDescriptor[73] = { 0x05, 0x01, // USAGE_...

Is there a way to simulate 2 devices with one avr ? My Problem: I want to develop a device wich is a gamepad with a led.But I dont want to develop my own gamepad driver. I want to send the report to switch led from an extern program. And the gamepad should be used from the normal gameport driver. In...

Ok, thats it. I think I have reached the knowledge that I have to use another interface. Maybee I use the USART which could do the 1Mbit and use one of this USB-Serial adapters. But my last thouth is: It could be posible to drive the avr with 18Mhz or 24Mhz. ( I know it would be outside Spec ) But s...

I tried: uchar usbFunctionWrite(uchar *data, uchar len) { return 1; } and in the main: int main(void) { for(;;){ usbPoll(); } return 0; } which should result in fastest transfer. But it dont goes over the 5kByte/s transfer speed limit. I ...

I think i tried this already: I send data to the AVR with: int ret = usb_control_msg(device, USB_TYPE_VENDOR | USB_RECIP_DEVICE | USB_ENDPOINT_OUT, USB_CMD_T6963_STREAM, 0xff, 0xff, (char *)mybuffer, bufferlen, 5000); in mybuffer is the data I send (254 byte). In the AVR is this: uch...
