Hello,
recently i've buit a new PC with an Asus Z97I-PLUS MoBo (mini-itx). When I shut it down the mouse light stays on and I'd like to turn it off without switching off the PSU. I enabled the ErP mode in the BIOS and I checked that the option that allows to charge usb devices when the PC is off was disabled. My PSU is a Corsair CX500M (modular) and its package says that it's Erp compatible. I haven't installed any utility such as Ai Suite. I use Windows 7 64bit.

Thank you for the support.

Yesterday I disabled the ErP mode and now the problem is gone. I had never tried this before becouse previously I had a similar mouse that had the same problem. When I started using the new one i simply left ErP on. How is it possible that when ErP is enabled USB ports work?
