Subject: DRS4 Evaluation Board + Powered USB Hub 

I am trying to use 4 evaluation boards with a powered USB hub (since eventually, I will have to do this on a laptop).  It seems like destroying the DRS object is insufficent to properly close the boards when on the hub (i.e. I get usb read errors next time I run my program). When all the boards are plugged into the computer, all is fine.  This is on Linux using libusb1. My guess is something about resetting the port doesn't work properly (but maybe that's this particular hub's fault?).  Has anyone else experienced a similar issue. If not, can someone recommend a hub that is known to work?
