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
