not up to normal Tripp-Lite quality
The USB-mini-B connector interferes with the case. Forcing it is not a good idea, as it will likely damage the connector or its solder joints. I've also had trouble with this hub recognizing thumb drives plugged into it. I may have received a lemon, but you cannot excuse the cable issue.
Note that I have several other Tripp-Lite USB hubs, all of which have been great. I keep a U222-004-R in my go-bag; love it. I'm a big Tripp-Lite fan. Hey, Tripp-Lite is the only company that ever put the switch on a power strip at the correct end (ie, opposite the power cord; not adjacent to it)!
