error in device mgr/usb "unknown device" . . the OS realizes a device has
been plugged in, but not what the device is . . . any ideas? Other
devices
like mouse, flash mem, etc are fine in the same physical port . . .
There is a handy free prog for helping you see, and manage, what usb devices
are or have been connected to your pc: USBdeview:

(I notice they now have similar progs for keeping track of wireless and
bluetooth too.)
I found it very helpful in trying to diagnose why my pc would recognise a
usb wireless adaptor, but laptop only did it for a few days and then
stopped. USB connections do seem to be rather temperamental, especially
when there is software on the device that has to be started and stopped
properly.
With our canon I deleted all the canon software from the pc in the end, and
just get at what is on the camera via My Computer (The camera does not show
up in the notification area as a usb device, just as a drive in MC)
(Do have a look at that usbdeview: you may be surprised at all the stuff
that has been connected at one time or another!)
