Hi Fred,
The first question I have to ask is whether or not you've installed the
drivers for the mainboard's chipset yet? The correct USB drivers that are
specific to that mainboard are a part of that set. If not, them you're only
running the ones that are suplied by XP, which are extrememly limited and
prone to issues. If those are already installed, try updating them from the
board's manufacturer's site.
Next, do you have any networked shares mapped to this system? There is
a known conflict that sometimes arises betwen USB drivers and mapped network
shares.
You can try running SFC (System File Checker) from a command prompt
using the following syntax. Just be aware that it only restores corrupted
files, not registry settings.
sfc /scannow
Finally (for now), have you done any reassignments of drive letters on
this system? If you've changed any drive letters, it could have been enough
to confuse the USB hub as to what should be assigned to the non-working
sitcks. Occasionally when Windows gets confused about something, it will
simply do nothing.
You always have the option to go into Device Manager (Start > Run, type
in devmgmt.msc & press Enter), remove all references to USB support (at the
very bottom of most), reboot and let Windows reinstall all of the drivers
and reg entries. Hopefully, something here will get your sticks back on the
job. :O)
Peace,
Gman
