I finally found a clue to what is causing this problem.
Opening the Device Manager (START > SETTINGS > CONTROL PANEL > SYSTEM), I discovered
that there are two entries for "Universal Serial Bus controllers". One of these has
the motherboard USB 1.1 devices, the other lists the PCI card's USB 2.0 devices.
Trying to correct this, I've discovered that the installation routine for the PCI
Card USB 2.0 drivers has (oddly) installed the USB 2.0 drivers in C:\WINDOWS\DRIVERS\OUSB2
instead of in the normal location for a driver (C:\WINDOWS\SYSTEM or C:\WINDOWS\SYSTEM32\DRIVERS).
The solution seems to be to update the device driver for the "USB 2.0 Root Hub Device",
pointing the update wizard function to C:\WINDOWS\DRIVERS\OUSB2, which corrects the
error in Device Manager.

all the USB 2.0 host controller and root hub entries (seven entries in all) during
boot-up.

Windows reinstalled the USB 2.0 controller on the PCI Card. But it didn't do much
good, as I am still suffering from the occasional reinstalls of the USB 2.0 controller
on boot-up, although the zero E error seems to have been cured.

quite normal, with only the entries I'd expect to see.
