====== Using USB in U-Boot ======

==== Initialise new connected USB devices ====

<code>
TQMa6x[MBa6x] U-Boot > usb start
</code>

==== Connected storage devices ====

<code>
TQMa6x[MBa6x] U-Boot > usb storage
</code>

==== Currently used storage devices ====
<code>
TQMa6x[MBa6x] U-Boot > usb dev
</code>

==== Partition information of USB storage device ====

<code>
TQMa6x[MBa6x] U-Boot > usb part
</code>

==== Read FAT file system of USB device (e.g.,  for USB device 0 partition 1) ====

<code>
TQMa6x[MBa6x] U-Boot > fatls usb 0:1
</code>

==== Read Ext4 file system of USB device (e.g., for USB device 0 partition 1) ====

<code>
TQMa6x[MBa6x] U-Boot > ext2ls usb 0:1
</code>

==== Read USB information from Kernel Ring Buffer ====

<code>
root@MBa6x:~ dmesg | grep -i usb
</code>

==== Mount USB Stick/HDD in Linux ====

If a USB device is inserted after booting, the kernel will automatically provide information about the recently connected device. Thus one can easily read which device is to be used for mounting. The first partition of the device is sda1.

==== Read UUID of USB Storage device ====

<code>
root@MBa6x:~ blkid
</code>

==== Mount /dev/sda1 to /mnt ====

<code>
root@MBa6x:~ mount /dev/sda1 /mnt/
</code>
