* Calmed down debug output a bit

Browse Source 
* Removed all friends in the USB stack classes (as they are not needed)
* Added max packet size to the pipe and respect it on transfers
* Use pipes with the same speed as the device

Device descriptors can now also be retrieved from full speed devices and devices with a packet size of more than 8 bytes. The devices are also correctly initialized to their default configuration.
