I've been moving it around (have 5 USB buses).  Haven't found a bus just by
itself yet that works any better.   I did the cat test and it did in fact
eventually hang on it too... so definitely a Linux kernel hdpvr and/or usb
issue.   Sadly I don't think I can get a PCIe USB card into this box.  Dual
GeForce 760 and a PCIe x1 SATA hot swap card.  I've been using the RCA
audio inputs all along on the hdpvr.
