first try at getting cdc acm working along size the HID
get cdc acm (serial port) kinda working (the main thing was to coalese the two interfaces into one - ".iface_assoc = &cdc_assoc")
driver file (inf) for CDC ACM on windows
Merge branch 'cdcacm' of https://github.com/djpnewton/kowhai_stm32 into cdcacm
got HID working:
 - usbd_register_control_callback called twice (each call specifies a single type of control request only I think)
 - the HID TLC read/write only seems to work when it has endpoint address 1 & 2
update makefile for stm32f4discovery specific commands
Merge branch 'cdcacm' of https://github.com/djpnewton/kowhai_stm32f4 into cdcacm
simplifiy for debugging
got CDC-ACM and HID working at the same time by changing the HID and CDC DATA endpoint pairs to use the same (bidirectional) endpoints
