First get into the usb. I think U: stands for usb drive. Then you can
simply use
nand-copy and nand-save commands to do that.

Just to add a few points: channel 1,6,11 are used by the mesh. These
are the three channels with least overlap. I guess we can associate a
XO with one of them to always look at that channel first. All three
appear even though thre is no mesh associated with it.
