Windows 7, 8, 8.1, 10 will not detect my P 21, P 30 and/or P 45 digital back

Last updated: 05-01-2016

Problem

The digital back is not detected by the hardware wizard and the driver can not be installed.

Solution

Go to the Windows Menu (Start button)
Find "Computer" in the list and right-click on it.
Choose "Manage" from the dropdown.





Select Device Manager from the left side. 
Right-click on the entry for the IEEE bus host controller and select "Update Driver Software". 




In the window that appears, click "Browse my computer for driver software". 
In the next window click "Let me pick from a list of device drivers on my computer". 



 


In the next window you will see a list of drivers, one of which says "1394 OHCI Compliant Host Controller (Legacy)". 
Select it and click "Next". Windows will then install the legacy driver.
 

*NOTEFor Windows 8, 8.1, 10 the "Legacy" driver is not available to select. You will need to download it from here
