USB2 reverts to USB1

  GRFT 09:07 03 Jan 07

I use USB2 flash drives for document backup: daily, incremental and weekly, full backup, using my own DOS batch files.
This works fine most of the time taking around two minutes for a full backup of 140mb, but occasionally it seems to revert to USB1 and then takes about ten minutes. This happens with any drive and no matter which socket it’s plugged in to.
There is no indication of anything wrong in Device Manager. (XP Home.)
Thanks for any suggestions on how this can be fixed.

Windows XP doesn't like old drivers, update the "USB2 Enhanced Host Controller" Driver, it may help?

Thanks, recap; I'll try that.
