I started designing a little device which uses the obdev USB implementation
For the communication between the host and the device I would like to use the control endpoint. The problem is that the USB-Prober on Mac OS X says that the device has no endpoints:
Device Class: 0 (Composite)
Device Subclass: 0
Device Protocol: 0
Device MaxPacketSize: 8
Device VendorID/ProductID: 0x1214/0x04E0 (unknown vendor)
Device Version Number: 0x0001
Number of Configurations: 1
Interface #0 - Unknown
Alternate Setting 0
---> Number of Endpoints 0
Interface Class: 0 (Unknown)
Interface Subclass; 0
Interface Protocol: 0
I guess this is not correct.
The documentation says that the control endpint is the default and is alwas enabled, isn't it?
Is there anything I have to configure? I used the PowerSwitch firmware and removed most of the code from main.c to get a basic starting point for my own implementation.
Here is what I call in the main function:
Code: Select all
usbInit();
ir_init();
sei();
for(;;){ /* main event loop */
usbPoll();
}
return 0;
What do I miss? I have tried other firmware implementations like the firmware for the IgorPlug, which shows me one endpint.
So, I think the hardware is basically ok.
Thanks!
