I am having similar problems with our Qu-32. Here is the process I had to go through to install the 1.9 firmware upgrade.
I loaded the firmware update onto the stick I have been using on the desk that I also use to backup scenes and EQ settings.
Plugged it into the desk to find the desk would not recognize that the stick was in the Q-Drive.
– I reformatted the stick on my Mac
– I the plugged it into the desk where it was recognized, and I reformatted it as a q-drive stick
– I again put the update file on the stick
– plugged it into the desk and was able to update the desk
However after the desk rebooted with the update, it again would not recognize the stick. I rebooted the desk several times to no avail.
I was out of time so I later the next day reformatted the stick on my Mac, plugged it in the desk where it was again recognized so I reformatted it and was able to copy all the backup files.
This is getting tedious.
