I got the cheapest kvm ($19.95 for IOGear) at Frys; may want to check
if I have any plastic endcaps that will fit the vga, unlikely; just
have to put up with a couple of extra cables dangling.
Checked the website & don't see any pics with all of the usb ports but
the text does say 1 type-A & 2 type-B ports. The type-B is that square
type that requires a "standard" usb cable. The keyboard & mouse
usually have an usb cable already connected & so won't work for any
switches that have the type-B ports for keyboard & mouse; unless
one wants to buy an extra adapter to change the type-A to type-B.
For regular devices, the type-B ports would be satisfactory.
Now to check for overrides of that crappy win7 64-bit enforcement
of device drivers......Nosing around the Max mini in command line
(terminal mode) & see alot of stuff familiar as in linux :-)
