|
The device needs to implement the Abstract Control Model (ACM)
|
|
subclass defined in the USB Communication Device Class (CDC)
|
|
specification. This protocol requires two USB interfaces, a data
|
|
interface which consists of two endpoints (bulk in + bulk out) and a
|
|
control interface which consists of one interrupt in endpoint.
|
|
Furthermore, on EP0 the device must implement the class-specific
|
|
requests defined by the CDC specification. Because this USB protocol
|
|
is compliant to the CDC/ACM standard on some other operating systems
|
|
(e.g. Linux, MacOS) the device can work with in-box drivers.

config USBHOST_CDCACM_REDUCED

|
|
---help---
|
|
This mode uses the CDC data interface (bulk in + bulk out endpoint)
|
|
only. No control interface (interrupt in endpoint) is required. The
|
|
device needs to implement the CDC class-specific requests, so that
|
|
is still possible to support baud rate settings and serial control/
|
|
status lines. This mode is useful if the number of available
|
|
endpoints is limited by hardware restrictions.
|
|
|
|
If the CDC/ACM compliant protocol is selected, then the reduced
|
|
protocol is supported for devices that provide not interrupt IN
|
|
endpoint. This option is then most useful for testing purposes or
|
|
if there are insufficient resources to support the compliant
|
|
protocol. The interrupt IN control interface will not be used even
|
|
if it is available in this case.

config USBHOST_CDCACM_BULKONLY

|
---help---
|
|
The device implements only the data interface (bulk in + bulk out
|
|
endpoint). The device does not provide an additional control
|
|
interface and does not need to implement any class-specific requests
|
|
on EP0. Because bulk transfer mode provides flow control, there is
|
|
no need to support serial control/status lines. The advantage of
|
|
the bulk-only protocol is that the implementation efforts on the
|
|
device side are reduced to a minimum.
|
|
|
|
By default, both the CDC/ACM compliant protocol and the reduced
|
|
protocol are supported. This option is then most useful for testing
|
|
purposes. The interrupt IN control interface will not be used even
|
|
if it is available; nor will EP0 class requestes.
