* ranges are specified (thanks to Thomas Bleeker)
|

* - Fixed CDC and RNDIS host demos and class drivers - bidirectional endpoints should use two seperate pipes, not one half-duplex pipe
|
||||
* - Fixed Pipe_IsEndpointBound() not taking the endpoint's direction into account
|
||||
* - Fixed EEPROM and FLASH ISP programming in the AVRISP project
