To many conections.... I sell the Keyspan and its very nice, but I only use it when I need to (I also have another model cheaper and more industrial and has Windows 7 drivers)
But when you start going from USB to adapter then to PCMIA then to the cable or device.... way to many conections for me, its asking for something to fail
You can sell you PCMK (to me
) then add some more money and buy a 1784-U2DHP this is the USB to Data Highway Plus they work very good, someday I hope to come out with something like it
