Mmmmm, I wonder if the problem may be the jump drive. I too have a
Lexar 1 gig that cannot connect to my Dell notebook. Works on the
other two computers here though. Also works on my grandson's. Is
there a common thread here?

As far as I know, the pins you connected your front ports to are
controlled
by the same chip as the rear ports. However it is possible that the
cable
or cables running to the front ports on the case are not wired for
2.0.

Ian (trying to bottom post as much as possible!)

Mine is a Lexar 1 gig. It works fine in the back ports on my 8KNXP,
but not the front ports. It works on my Dell laptop and in the front
ports on the IBM desktops at work.

Wonder how we can find out about the front port wiring to see if it's
correct, or if they even support 2.0? A jump drive is one of the
things that the front ports are the handiest for.....

What case do you have? We are talking, aren't we, about ports built onto
your case with trailing cables terminating in pins or blocks for
connection
to the headers on the Gigabyte board? Just to be clear! ;-) The header
pins for either USB standard are the same to all intents and purposes, but
a
port, hub or cable can still be incapable of operating at USB 2.0 speeds.
In such cases only USB 1.1 speed is achieved. Since you achieve USB 2.0
hi-speed with the drive on your rear ports, I still suspect that the
socket/cable provided with your case cannot handle 2.0. It is sometimes
possible to replace these, but you are into specifics based on whose case
you have used.

You could go to EBUYER and purchase their internal USB 2.0 7-in-1 card
reader! As well as reading cards, it has a USB socket on it, which is
certified 2.0. It's a useful peripheral, and connects to the same USB
header
on the motherboard. What's my point? It is to stop using the case front
ports, and replace them with another certified USB 2.0 device that
provides
a USB socket.

Here is a really useful source of USB information:

Thanks for the info. Yes, we are talking about USB ports on the front
of the case. It's a Antec case with a little door on the front with
two USB ports and a Firewire port.

Funny thing is that I have a old USB 1.1 hub plugged into a port on
the back of the PC, and the Lexar Jumpdrive works fine in that hub.
But it's a unrecognized device if I connect it to the ports on the
front of the case.

I looked at a bunch of things on that web site. The idea of some front
USB/Firewire ports combined with a card reader, mounted in a drive bay
is VERY interesting. The only one I saw on that site also had a bunch
of other stuff like temperature displays and fan speed controllers;

It doesn't have any more UBS/Firewire ports that the front of my case.
I would love to have something like that with more ports and card
readers, and no overclocking gizmos.

I have a an 8KNXP and Antec case. I think when I built it there was an
addendum to either the case or motherboard manual about errors in the USB
wiring. Possibly a polarity switch.

Adrian

Thanks for the reply. I just checked all my documentation and I did
not find any addendums. I left a message on the Antec and Gigabyte
support sites.

I wonder if it would hurt to try swapping the D+ and D- polarity?

Thanks

Don
