I've got a pair of CDJ 850 K players. The rekordbox connection works as does the CD player. However, I can't get it to read any USB sticks.
i've tried 2.0, 3.0, various different makes
I've reformatted the USB sticks with Master Boot Record in Fat32, Fat16 i've also tried ExFat. (Formatted on a Mac)
I'm running firmware version 1.12, and have tried upgrading to 1.13, but when i follow the instructions (Hold USB and RELOOP as you power up), I don't even get the 'Usb Connect'.... I get a a message that displays the Firmware version after about 10 seconds.
Also when the CDJ is first turned on, the MENU/Utility button doesn't work either
