usb should be fat32 formatted, put it in the 7200 and then use show storage to check it has mounted.
(sg-7210) #show storage
Filesystem Size Used Available Use% Mounted on
none 2.0G 18.6M 2.0G 1% /tmp
/dev/usb/flash3 1.5G 110.3M 1.3G 8% /flash
/dev/usbdisk/slot0/1 7.4G 186.0M 7.3G 2% /mnt/usbdisk/slot0/1
(sg-7210) #
note the "partition" number, here is 1 (i.e. /mnt/usbdisk/slot0/<partition #>).
then, you can use CLI as follows:
>> put something on it
(sg-7210) #copy flash: default.cfg usb: partition 1 default_11jan15.cfg
....File default.cfg copied to /mnt/usbdisk/slot0/1/default_11jan15.cfg successfully.
(sg-7210) #
>> perform directory listing
(sg-7210) #dir usb: partition 1

Note: If you want to use the front panel to do the upgrade, you need to ensure the image is in a subdirectory called Arubaimage as noted in the userguide in the section "Using the LCD Screen", but if you just want to access and use the USB after the controller has booted, then this doesn't have to be the case.
