Thanks for the feedback. Do you by any chance have any USB type Mini PCI cards installed internally? I initially noticed the issue with a mini PCI LTE modem card. Then I realized it was a more generic USB problem; I believe the apu2 has USB1 and USB2 ports, the apu3 has two USB3 ports externally, and then the mini PCI and a couple of internal headers are USB2. The USB3 ports, using the xHCI driver, work fine, I suppose in the worst case I could use an external Mini PCI to USB adapter and plug the card in outside of the case, but that just seems so kludgy <sigh>. I actually found a friend locally who had a apu2 board, he couldn't get the LTE card to work on the internal mini PCI slot, which also appeared to be EHCI based, and it would sometimes work and sometimes not plugged into the external USB ports. It was really weird, when plugged into the same external port, sometimes the device would show up on the EHCI bus (and not work) and sometimes it would show up on the OHCI bus (and work). He didn't seem to have any trouble with USB flash drives on the EHCI bus on his apu2 though.
