=== Description ===The [[AXEL ULite SOM/AXEL ULite Evaluation Kit | AXEL ULite Evaluation Kit]] provides two USB ports, one Host and one Host/OTG optional ports: * J11 is a standard USB Host 2.0 Type A connector [[File:AXEL_ULite-EVB-USB_Host-connector.png|thumb|center| 500px|USB Host connector]]

''Jxx'' * J22 is a ''TBD:connectormicro-AB type'' header connector receptacle for the RS232 two-wires UART3 an optional USB Host/OTG connection: this interface can be mounted on request and provide an Host or an OTG USB additional port, used for debug purposes (bootloader and operating system serial console).:

The following table describes the interface signals:  ==== USB Host ====

|J11.1,2,4,6,,7,8,10| -| NJ1.A.188 || USB_HOST_VBUS || VBUS | N.C.| Not connected

| 3J11.2 || J1.189202 || USB_HOST_DN || RS232_RXUSB Host Data - | Receive line|

| J11.3|| J1.187200 || USB_HOST_DP || RS232_TXUSB Host Data + | Transmit line|

| 9J11.4 || -|| DGND|| Ground||

=== Device mapping = USB Host/OTG ====UART3 is mapped to <code>/dev/ttymxc2</code> device in Linux. The peripheral is used as the default serial console, both for the bootloader and the kernel.

To connect to the debug serial port=== Device mapping ===The USB Host ports can be used under Linux for connecting USB peripheral devices: # connect the DB9 adapter bracket related peripheral driver has to be integrated into the J22 connector on the SBCX board# connect a serial cable between DB9 connector and PC COM port through a NULL-modem cable (not provided)# start your favorite terminal emulator software on PC (eg: PuTTY); communication parameters are: 115200,N,8,1Linux kernel.
