View source for EHCI Gadget Debug

== Introduction ==
This page is about using embedded GNU/Linux devices in order to get the USB debug logs.

== Howto ==
=== Compiling ===
* You need to be familiar with (cross) compiling your kernel.
* (Cross) compile it as usual but during the configuration do the following:
Go into Device Drivers:
 Device Drivers  --->
Then go into USB support:
 [*] USB support  --->
Then go into USB  Gadget Support:
 <M>   USB Gadget Support  --->
Then enable the following option:
 <M>     EHCI Debug Device Gadget
Then select the printk option for now(a bug has to be fixed to make serial option work properly):
         EHCI Debug Device mode (printk)  --->
=== Loading ===
Remove all usb gadget drivers such as g_ehter or g_mass_storage with rmmod then do:
 modprobe g_dbgp

=== Finding the USB debug port ===
See [[EHCI Debug Port#Finding the USB debug port]]
