OK... I recently updated the UC to version 188.8.131.52213 which offered a firmware update. After checking what the firmware update improved, I decided to update to take advantage of the retention of the 48v power setting. Apparently the update failed and now I am stuck with a non-working audio interface.
I am in contact with Presonus technical support on this but, the back and forth communication is very very slow. Painfully slow! On their suggestion I reverted back to UC version 184.108.40.206221 to get the "Update Anyways" option. I even installed older versions of UC (1.5, 1.8, & 2.4) to try and get that "Update Anyways" option. So far that option has not appeared.
The last thing I tried per tech support instructions was to manually remove the 192 from my Win 10 PC (with the latest updates) completely in device manager. The 192 was reinstalled with UC version 2.8 and the connection was moved to a USB 2 port. Still no "Update Anyways" option is presented.
So... day (4) without a fix.
Does the forum have any other thoughts, ideas, suggestions for how to get this baby working again? I appreciate the Presonus technical support but, it really is way too slow going back and forth through the support ticket system (like emails). I wish they had telephone support so I could get this fixed or, at least know if this is going to need repair, or if it is bricked forever. Thank you.
