Excellent question Mike.
This laptop runs Windows 7 Home Premium, the 64 Bit native variety.
There are stories on the site for the (now discontinued) NSLU2 device for Linksys, http://tech.groups.yahoo.com/group/nslu2-linux/?yguid=235165590
as it was discovered that the thing ran Linux, that the cables people were recommended for using for its serial ports, it was discovered that the Windows drivers for the gizmo that people chose, a Cell to computer cable, had instabilities. (Actual home page http://www.nslu2-linux.org/
People were advised if they were going to do any work on their devices, they should either use a system running Linux, or failing that a Live-CD of such a system because of that. There was also some issues concerning the actual chipset itself, but that may have been falsely attributed.
Oddly enough the FTDI ones do not have that problem. I've used one such gadget originally made by Parallax for their Basic Stamp devices for hours without any problems, both for the Stamp kit, and for other uses.
