USB drive disconnects on wake

[bbiktop]

Hi there,

Encountered a well-known (to anyone except me till now) problem: usb flash drives disconnected after wake from sleep. Changed BIOS XMP profile disabling it, and the problem has gone, flash drives are still mounted on wake. Tried to change bios settings, like erp, platform power management etc - the same disconnect. With XMP on - flash drive disconnected on wake. With XMP off - all works fine.

My questions are:

How is it related to each other? Why xmp causes usb to disconnect (probably losing power on sleep or something)?

How to fix it making xmp and wake work together without usb drives ejecting/disconnecting?

Thank you

Ok, is there a known way to fix that? I have it always, not in some cases. I do not understand at all how could memory frequency profile influence to usb sleep.

As I wrote, tried both enabled and disabled - does not work. Any other suggestions are greatly appreciated!
