Hello fellow victim of Tripplite braindead USB!  There is a solution!

My blog on diagnosing the problem:

My blog on packaging the solution:

Solution on github:

Sadly, you will have to buy a USB standard conforming powered hub to
make the Tripplite work.  These are suprisingly hard to find, but the
solution includes a list of known working hubs.  I use a small visibly 
powered USB device like a light or fan to test whether the hub really
works.  The manufacturers like to break things without changing the model #.

Be sure to leave a critical review on wherever you bought it from, 
hopefully Tripplite will eventually fix it.
