VEXos utility update error

Hi Everyone!

I tried downloading an update to my brain via USB, and the screen for the update will pop up for one second but then it will say connection failure. All my sensors are properly plugged in, and I tried to take out the USB, wait one second, and then connect but it doesn’t work.
(I have a first-gen brain for VEX IQ.)

Any help?
