Thanks for the reply, I feel a little better about seeing this although I am curious about something.
Is this behavior specific to the U2410 or Dell media card reader equipped monitors? The reason I ask is two-fold: 1) I don't recall running into this when using an older, non-Dell monitor that was equipped with USB ports and a media card reader, 2) USB devices can be hot-swapped and as seen with a USB flash drive the storage device can be "visible" only when the storage device and media is actually connected.
My thought is that an internal USB media card reader can mimic USB insertion/removal (switchable pullup resistor?) when a media card is inserted/removed and that may be why the one monitor I used didn't report a USB storage device when no media card was inserted. My other thought is that in order to simplify design such behavior is dispensed with in some (many?) internal USB media card reader designs and that is why the U2410 (and other Dell monitors?) exhibits the behavior. Have any experience and/or thoughts on to share on that?
FWIW, disabling the U2410 media card reader's associated USB storage device in Device Manager has eliminated the "ghost Windows volume" and more importantly to me it prevents an empty media card reader from triggering a safely remove hardware tooltray icon. That icon is my reminder that I accidentally left a storage device connected and need to grab it before I leave :)

That is all normal. The OS has to be prepared for when/if you were to insert a card.
