Attention: If devices attached to the express card aren't recognised after a restart of the computer, it is advised to detach and reattach the devices onto another USB port again, so a proper recognition is realised.

If the card doesn't work properly from the start, you may try out the following steps
Step 1: de- and reattach the devices to be recognised, so the system can try another recognition search
Step 2: Augment with the optional power supply, so an automatic search can be retried
Step 3: Check the PCI-E socket on the main board for possible faults
Step 4: Try out another Desktop PC, if available, to determine the card's general functionality
