Wow.. You are amazing. Thank you! That helped. I had pwm hub on the same cable. Now it's just pure psu -> pump.

As I said, USB setup is fine. If I change ErP setting back, then it would alarm constantly.

Hi, I have a problem with my D5 Next pump. The pump makes the alarm for a couple of seconds after I turn off my PC. The MB is X570 Aorus Pro. I have newest pump firmware and enabled ERP option in bios, witch causes disabling USB power if PC is off. I've reach out local forum and one guy has similar problem, so he replaced electronics in pump and that solved the issue.
