Fork of USBHostWANDongle_bleedingedge by Donatien Garnier

USBHost/USBDeviceConnected.cpp@9:c9e9817c398c, 2012-07-31 (annotated)

Revision:
9:c9e9817c398c
Parent:
2:a8b2d0cd9bbd
Child:
10:08bce4cd973a
Renamed Endpoint->USBEndpoint because it conflicted with the Socket API! Made some weird symbols mixups happen that made everything explode when the first USB endpoint was allocated.
