[nfbcs] USB A/B switch

[Tracy Carcione]

Has anyone tried a USB A/B switch with a braille display?  It would be 
handy, if I could connect my Alva to either of my computers, and switch on 
the fly, but the reviews on Amazon of A/B switches said they were pretty 
hit-and-miss.  Also, when I turn off the Alva and move the cable, I have to 
close and restart Jaws to make Jaws see the display again.  Would the same 
be true with the A/B switch?
Thanks.
