My usb wount load into my rx3.

Hello! I have recently lost my USB and went out to buy a (PNY elite steel 256GB  3.1 USB). i put the songs from my harddrive into the USB, and it worked fine on my computer. but when I put it into my RX3 it won't load and says E-8307: Device no response and doesn't load. 

do I have to wipe the USB, put it in a new format and try again? i have tried to move the database but I'm not sure how to convert the library to rx3.

please help, I'm desperate!
