I'm trying to get VUSB working on an attiny44, where INT0 is on portB, and portB has no other usable ports when an external oscillator is attached.
Would it be possible to doctor the code to support D+ and D- being on different ports? - at the moment the setting "USB_CFG_IOPORTNAME" only accepts one value.
I feel like this would not be a huge change if I knew where to look!? - any pointers would be appreciated ....
