I just got the QU-24 and want to update it to 1.4. I bought a small thumb drive to transfer the upgrade, but the QU-24 doesn’t see it at all. I put the TD in every computer I have and they see it without a problem. I can’t format it, since it doesn’t even recognize it and ungray the Format button. Searching this forum, some have said to power up with it in the QU-Drive slot. This didn’t work either. Do I need to buy another one and hope it’s compatible? Any suggestions?
