In my experience they just work. The only problem I have had (I have
three around) is that the older ones do not appear to support some new
format memory cards (Memory stick pro duo in my case). By older ones I
mean the card readers I bought some years ago. A card reader that I
bought around a year and a half ago reads all of them. Upon close
examination I have noticed that the newer ones specifically mentiond
Memory stick/pro duo on them. I supposed memory stick card reader slots
are not backward compatible (Sony, what a fiasco!).

Other than this, these kind of USB card readers have turned out to be
the most robust method of reading various memory cards.
