Would someone (advanced computer user) who is having the USB connection failing problems with Windows XP be willing to try this please?
With the PEz cable connected to a Mainboard port (not an external hub)
and the "USB Connection" mode on the PEz enabled ("USB Connection" screen showing).
Open the device manager and see if there is a "..Enhanced USB2.0 Host controller.." (slightly different wording from the others in the list)
Important: File safety, there should not be any other USB storage devices connected.
Right click on this device and
Disable this device.
Windows should re-discover a device (which is the PEz) with in a few moments. (Which happens to be the device just below the highlighed line)
I have now disconnected and reconnected many times, Used Calibre to update the PEz.
