It might be possible if you used a Y connector USB lead and powered the drive from another device (or powered USb hub)

It would be a faff even if it worked though (and it's one of those yoou'd have to try it to see if it worked ones)
Just get a USB flash drive and use that as a go-between. decent size flash drives are so cheap these days (link in next post because AB doesn't allow two amazon links in one post).
