Hi,
I have Sandisk extreme pro usb 3.1 formatted in FAT32 and CDJ850 (v1.13 latest firmware).
When I plug in my USB I get the "USB ERROR" on the screen and it doesn't work. See screenshot.
How to solve it?
The official word is that the CDJ-850 was released prior to USB3 becoming mainstream, and as such, we can't guarantee universal compatibility with USB3 devices You may find some drives work and some don't - some may work with FAT32 and others may only work with HFS+. Sorry!

Is the filesystem also set for MASTER BOOT RECORD? If not, you may receive that error.
Yes filesystem is MASTER BOOT RECORD.
i have exactly the same, sometimes it does show the contents, but when i want to play a file, it gives the 8306 error. but i didn't remove any file as that error suggest, 100% sure
i tried everything i found here and on google, the only thing i can think of is that 850 don't work with USB 3.1, but the same stick does work perfectly on a 350 (!)
i bought these sticks exactly because everyone says it's the best, i really feel silly having bought a 850 and not being able to use it :'(
This is very bad, I just bought 2 of them as they were recommended on this forum. They are expensive and I have cdj850 and club has cdj850...
Pioneer, please make a firmware update for cdj850 on this issue!
for my case it'd like to add i'm on a mac and all files are .wav 
i finally got it to work on the 850 with a sandisk ULTRA 64GB which is 3.0
so after a lot of testing, i can confirm the 850 doesn't work with either 256GB sticks nor 3.1 (extreme pro) sticks,
can you please fix this Pioneer? thanks in advance
same usb worked perfectly on cdj2000 for me. so yes the reason is cdj850. looking forward for the firmware update!
