USB host


Linux Kernel Configuration
└─>USB host
In linux kernel since version 2.6.12  
This option enables the host functionality of the ETRAX 100LX
built-in USB controller. In host mode the controller is designed
for CTRL and BULK traffic only, INTR traffic may work as well
however (depending on the requirements of timeliness).
