This package provides a suitable eCos device driver

In this version the driver will support the AT91SAM7S.
Other AT92 devices may work, but have not been tested.
The Driver needs 48, 96 or 192MHz plus minus 0.25%.
Buffers are allocated only in the higher level. There
is no need to configure the endpoints in this CDL, because
they will be configured dynamical at the set_configuration
call from the host...
The endpoints 1..3 can be configured as bulk or interrupt
IN or OUT endpoint. Isochronous transfer is not supported."
