|
|
EG20T PCH is the platform controller hub that is used in Intel's
|
||
|
|
general embedded platform. EG20T PCH has USB device interface.
|
||
|
|
Using this interface, it is able to access system devices connected
|
||
|
|
to USB device.

|
USB device is a USB peripheral controller which
|
||
|
|
supports both full and high speed USB 2.0 data transfers.
|

|
This driver dose not support interrupt transfer or isochronous
|

This host controller driver emulates USB, looping all data transfer
|
||
|
|
requests back to a USB "gadget driver" in the same host. The host
|
||
|
|
side is the controller; the gadget side is the device. Gadget drivers
|
||
|
|
can be high, full, or low speed; and they have access to endpoints
|
||
|
|
like those from NET2280, PXA2xx, or SA1100 hardware.
|
||
|
|
|
||
|
|
This may help in some stages of creating a driver to embed in a
|
||
|
|
Linux device, since it lets you debug several parts of the gadget
|
||
|
|
driver without its hardware or drivers being involved.
|
||
|
|
|
||
|
|
Since such a gadget side driver needs to interoperate with a host
|
||
|
|
side Linux-USB device driver, this may help to debug both sides
|
||
|
|
of a USB protocol stack.
