    I found one of my usb cables being 'smooshed' between my A-pillar and my dash. That was the cause of my USB port droppinbg connections constantly but still providing power. Don't know why, since the cable wasn't kinked, it was literally just smooshed. But give it a shot, as soon as I released the pressure that was on it, presto it worked like a charm again... ?

    EMI from the pressure on the cable? I never had EMI problems in my desktop except my optical mouse goes fritzy when I turn on my case lights (VU controlled LEDs)

    Oh yeah, I only support USB1.1.
    This shouldn't happen if you're always plugging back into the same port. It might if you're plugging it into a different port. This is because (if I recall correctly) the registry attaches drivers to ports. Since various devices might use the same port, the registry will also stack multiple removable device drivers on the same port - which makes sense since it's not uncommon to hot-swap devices on USB. If you move the device to a different port however, it will also have to install the driver there as well.

    These same rules also generally apply to PCI (except the hotswapping of-course). If you move a card to a slot where you've never installed a particular PCI card, you'll have to install the driver again for the new slot. If you move it back again however, it won't ask to install the driver.

    Im not sure if it was EMI or not, it was pinched about 4 feet from the hub, but it killed ALL my hub devices. So it maybe have been a short of some sort, who knows?

    I think it may be because I plug it into to a hub that has nothing else plugged into it, so I plug it back into a different socket each time... each time I reload the driver it assigns it a different COM #.

    It's no big deal, though. It only gets unplugged when I'm working on the wiring and stuff.

    thats interesting to me...because my usb wire is smooshed bigtime. I have it pressed between the back seat and the metal frame behind it. I wonder if that is why I'm having the same problem as you.
    But then again..I would think it would do it more-so when I have people sitting in the back seat. But thats not the case.

    Take a look at this thread that I started. It may be a help you people who have devices that will work if they are re plugged in.
