I have just built a new PC using XP Home/SP1 and have USB 2.0 ports on the
back and front. The motherboard supports up to 8 USB 2.0 ports. When I
insert my Thumbdrive (2.0) in one port it works at 2.0 speed. When I insert
it into another port I get a message saying a high speed device has been
plugged into a low speed port. I have tried uninstalling and reinstalling
the USB hubs but get the same results. I have also tried to install the USB
drivers that came with my motherboard and get the same results. Any ideas as
to what is going on.

Hi, Charlie.

Congratulations on your new mobo/PC! My new EPoX 8KDA3+ also supports 8 USB
2.0 ports. Four are on the backplane and came already wired up. The other
four are supported by two sets of pin headers (2 ports each) on the mobo, to
which I had to attach plugs leading to the 2 ports on a backplane bracket
and 2 ports on the front of my computer case. (My old mobo came with only
USB 1.1, so I had added a 4-port USB 2.0 PCI card to it; since I didn't want
to leave an empty slot in my new backplane for air and dust-bunnies to come
in, I've plugged in that card, too, so I now have 12 USB 2.0 ports.
Woohoo!)

My USB devices are a mixture of 2.0 and 1.1. My thumb drive is 1.1 and I
haven't plugged it in since I upgraded the mobo. Let's see... Yes, a
series of messages appeared in my Notification Area (SysTray) and now my
"new drive" is installed. I've moved it to several other ports and they all
work smoothly; the thumb always shows up as "Removable drive (G:)". My SD
card reader (2.0) is recognized in either the back or front slot with no
complaints.

I don't know what might be causing your port to be seen as low speed, but
maybe my comments can help you narrow it down. What make and model is your
mobo? Maybe some ports are low-speed, but that seems unlikely; if some are
high-speed, all should be high-speed.

Two possibilities that I can think of as well:
1) Make sure that they are all on HiSpeed in the BIOS. It is possible
to have half USB 1.1 and half USB 2.0 (but that would be an odd option
in the BIOS and definetly not a default).
2) The pins are set up wrong on the motherboard for the USB connector.
This would only pertain to the front panel USB connectors. If you have 2
slots on the front and one works, but the other doesn't, check and make
sure both are connected the same.

Great Call ! I checked where the USB connector attached to the front panel
and it was one pin off. It was hiding behind another plug and very hard to
see. I had been focusing on the stub on the motherboard. Every thing works
great. Thanks.

Hi, Charlie.

Thanks for the report back, and congratulations!

On my Enermax case, the cable for the front USB connectors has 8 individual
plugs for the 8 wires, rather than a single formed plug with all 8 wires.
Given the close quarters (especially since I have to put the mobo into the
case before plugging the wires) and my fumbling fingers, it's no easy task
to get all 8 wires onto the right ones of the 10 pins (leaving gaps for the
missing key pins). :>( That's about the only complaint I have about this
elegant little case.
