One issue that someone obliquely mentioned in the various
replies that I feel requires greater emphasis, is that the
SignaLink USB box is, first and foremost, a sound card
and as such requires a great deal more current than a typical
USB device and should be plugged into a *powered* USB
hub.
The newer Trimble Thunderbolt requires +24VDC, but some of the
older units on E-Bay, etc. may require +5VDC, +12VDC and -12VDC,
which can be obtained from a simple/inexpensive power supply.

Is it actually that easy to install?
Yes, it is. Just remember, you really do want to use a
static mat and wrist strap whenever you open up your K3 to
work on something internal to it.
