Thanks to Alan's help and the pointer to the manual that he provided, the devices can now be detached without creating an error message. I had searched for that document number and only got an Operator's manual as the result. I guess searching Documentation was not the right thing to do when looking for s document ;-)
After reviewing the sense data documentation and suggesting that they turn on bit 1 of sense byte 2 (The control unit is in communication with the device), success was achieved.
