    [SOLVED] USB mass storage (of any type) unreadable except in one port

    For the sake of closure, it turns out the motherboard was bad. MSI support was worthless, but AMD stuck with me -- slowly, but always asking good questions and eventually responding. They asked me to flash the latest (beta) BIOS from MSI and that bricked my motherboard (wouldn't POST, debug...

    [SOLVED] USB mass storage (of any type) unreadable except in one port

    Interesting, haven't seen the pnputil before. The thumb drive wasn't listed, perhaps because storage devices use the default MS drivers (usbstor.inf and .sys) . My mouse and keyboard were also not listed, I assume for the same reason. The INF filename is actually in the USB Tree View tool, too...

    [SOLVED] USB mass storage (of any type) unreadable except in one port

    Thanks but that didn't change anything. I only have a USB keyboard/mouse so there's only so much I can delete/uninstall (had to leave one hub for the mouse, at which point I could use the on-screen keyboard). I've had the most recent BIOS and drivers installed this whole time and they haven't...

    [SOLVED] USB mass storage (of any type) unreadable except in one port

    That's a pretty cool tool, thanks. I put the details of the working port into Excel side-by-side with the same device in a non-working port. The device ID in the non-working ports looks weird, it has an apostrophe, 03063190300004'5, versus the working port's device ID 0306319030000475. I pulled...

    [SOLVED] USB mass storage (of any type) unreadable except in one port

    Thanks. On this board it's called "ErP Ready" and it was disabled by default and is still disabled. In this case it's documented (same page in the PDF mentioned earlier, actually).

    [SOLVED] USB mass storage (of any type) unreadable except in one port

    Thanks. Interesting, that PDF is much better than the physical manual that came with my board (and yes it's the right one). Unfortunately changing to Auto had no effect on the problem. I also realized I should have USB XHCI Handoff disabled (seems odd it's enabled by default), but that didn't...

    [SOLVED] USB mass storage (of any type) unreadable except in one port

    This one has me baffled... I have built a new machine running Win10 Pro x64. With nothing else installed and all settings bone-stock (i.e. not overclocked), Windows can only read USB storage device filesystems from a single USB front-panel port. I have tested with multiple known-good thumb...
