Just got this error on my Model Y, Ive been using the same SSD drive for 2 years now, the car wont recognize any USB stick plugged in. USB-C still providing power to the wireless charger. I dont have anything else plugged in, just the OEM wireless charger and sentry drive.
I tried using different USB drive, restarting the car. Car wont recognize any USB data anymore at all. I checked on PC and the drive is working fine, so it must be the car. Got appointment for a few days from now.
