Stefan, I forgot to say what inputs I use for USB: PB2 USB-, PB3 for USB+ are you sure, that you do not enable the 2nd UART's transmitter or receiver unit? As these use PB2 and PB3, this might be the true reason for your problem. I use AVR-USB on a Mega162 and it works fine, even when timer2 overflo...

OK, then where are that users ? Why they are silent ? Here is no one why had success in this situation. Sorry, I don't see any reason for not keeping silent! Yes, I managed to get the AVR-USB code working, using Int2 on a Mega162 and it only caused me about one hour to get it working -- so what? Do...

The code will work with Int2 (I've done that with an Mega162).
But beware: Int0 and Int1 have a higher priority than Int2. This might cause some problems, when using these Interrups.

Are you sure that the 8515 has an Int2? Or do you mean the Mega 8515?

Sorry, forgot to log in...

thanks for your answer!

As you never observed similar problems, I checked the usb kernel drivers on my Linux system. After using usd-ohci.o instead of ehci-hcd.o everything works just fine!

Dear all, I use AVR-USB for the implemetation of a special interface converter for the Hameg 81xx measurement devices. As I do not want to poll the interfaces permanently, I implemented the interrupt-in endpoint. Everything seems to work quite well, I was able to use libusb's usb_interrupt_read() fu...
