No command to support what?

Maybe you can rephrase your question so I can parse it?

What exactly are you looking for?


USB is just a protocol to attach external devices,  so  depending  on
which  sort  of  devices  this  is there may be methods to download a
kernel. For example, if it's  a  USM  memory  stick,  then  you  will
probably  have  a  file system on it, and you can use one of the file
system access methods to list or load a file.
