Yer. They released a firmware update with USB compatibility but obviously not everyone is going to have that update installed, and it probably has some bug in it
Worst one I've had is when this chick hired a massive venue and barely anybody turned up. And was mostly fam instead of drunk 18yr old friends. Hnnnng moment
also i think some usb 3 shit still bugs out a bit on pio players. Depends whether the club has firmware updated or not etc. which isn't really a risk worth taking
I've found the sandisk sticks are pretty good. But all flash drives get slower over time. I think they are prob all pumped out from the same factory anyway. I just like the sandisk ones. Also transcend. They both do the job
