| |
Hi.
Due to some problems with the EHCI in an IXP465, I have found that this micro has an "on the go" feature. One of its features seems to be an "Embedded Transaction Translator", that seems to be quite "propietary".
I see in ehci.h, that using CONFIG_USB_EHCI_ROOT_HUB_TT, a function called "ehci_port_speed" has been added, and the comments suggest to implement the particularities of each controller with other functions.
The question is: - Are there many different implementations (it seems there are not, because I cannot see code for each of them... unless they are so particular that they do not even use the general interface)? - Is there any place comparing the similarities / differences between them?
Thanks
