I've never tried that on my A20, and usually routers are not enabled to do that. Matter of fact, even 'portable' external drives that take power from the port will cause problems.

You could give it a try, but don't be surprised if it doesn't work or does cause some problems with the workings of the router.

@IrvSp Thanks .. for now it seems I've found a work-around so that I may not need to do this, but still curious. Maybe I'll give it a try and see what, if anything, happens.
