This package provides a suitable eCos device driver

64 |
|
|
for AT91 USB.
|
65 |

|
In this version the driver will support the AT91SAM7S.
|
66 |
|
|
Other AT92 devices may work, but have not been tested.
|
67 |
|
|
The Driver needs 48, 96 or 192MHz plus minus 0.25%.
|
68 |
|
|
Buffers are allocated only in the higher level. There
|
69 |
|

is no need to configure the endpoints in this CDL, because

70 |
|
|
they will be configured dynamical at the set_configuration

call from the host...
|

The endpoints 1..3 can be configured as bulk or interrupt
