Front USB issue on newly built computer

<< < (4/7) > >>

I checked that but also, it's impossible to screw up, the connectors are not separate.  It is a single connector for the 4 wires.  And again, remeber that it is happening with at least two other computers.  With different MB.s and headers AND 2 different cases!  I am almost thinking now that it is a USB port power issue.  I have a powered External Hard Drive Enclosure (MadDog) and it works fine attached to the front ports.  I also have a standard 256 MB thumb drive with no software peloaded, and it works fine.

It is possible to screw up - the 4 wires can be in the wrong order even though they are in a single connector.  Can't imagine it being screwed up on two cases with different mobos and headers and working for some devices and not others.

Shot in the darK - I've had WinXP crash with a thumbdrive plugged in and not be able to find the IDE HD.  You might try disabling "Boot From USB" in the BIOS.

Also, there might be a BIOS settings for whether the ports are on all the time or not - +5V or Standby - although that shouldn't matter either.

Often the front ports are on a different bridge chip, so that might accont for it, but probably not on two different PC's.   :angry:

That's exactly my issue, different mobos, different pc's and same issue.  I am really stumped.  Ill take a look at the bios, but not sure if that will do the trick.

Look here:  http://www.directron.com/installusb.html

There are two different wiring standards for internal USB headers shown.  There might be more out there.  IF that's your problem, it's entirely possible that both cases are mismatched to the headers on your mobo.  The mobo's manual ought to have a wiring diagram showing the pinout of the headers.

If that's NOT the problem-  Did you get the exact same model of mobo to replace the first one?  Perhaps your problem is simply that the controller for the front USB on that specific model of mobo doesn't work quite right with certain hardware.  You might check the manufacturer page or Google looking for that.  There might be a BIOS update that addresses it.  Or you might just need a different model of mobo.

tommy:
This happend to me when i built my PC, the custom case was not made well and connecting anything other than from the mobo itself was kinda worthless.

Also, maybe your bios is set to not keep the settings from anything other than connections directly coming from the "main" USB ports. Might be worth a bios check.
