Hello,
I just recieved my Griffin USB-Audio hub in anticipation of using it with my new interface, the tascam us-122. I do not yet have the interface. so I can't comment directly on its intended use, but just the use in general. The hub itself is well constructed, and comes with a slimline wall wart. The included USB a-b cable also is quite sturdy. For these merrits alone, I feel as though I've justified my purchase. It cost $40.00 via Griffin's web site, which is comparable to other powered hubs. I'll post back with more information once my US-122 arrives.
