Device Control (Card Readers)

Question

I'm getting a lot of events for "Multiple Card Reader USB Device" being blocked by the Removable Storage policy. 
 If i add an exemption for these devices, should the policy still continue to block any devices plugged into the card reader device? (eg SD cards etc)

Hello Buck, 
 the multiple readers normally create one empty device per slot as soon as they are plugged in (even without an actual media inserted). And when these devices are disabled cards that are subsequently plugged aren't recognized. If they are not blocked (exempted) insertion of a card is a volume mount that is AFAIK not subject to Device Control. Did you test it?

Hello Buck, 
 in simple terms it's up to the device and its driver whether it's present without a volume mounted or not (a CD/DVD drive is usually "there" without a disc) and if it is there at startup DevCtrl will detect (and potentially disable) it then, and not only when a volume is inserted.
