Hi,
    I  have a ASUS AIO V222GA and another Acer Desktop XC-830 both
have Intel CPU J5005 and they both hit the same problem. The XHCI
connected USB keyboard/mouse can never wakeup the system from suspend.
It reminds me that similiar thing happens on ApolloLake too which
needs the XHCI_PME_STUCK_QUIRK to get it work. It's also mentioned in
https://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/pentium-celeron-n-series-spec-update.pdf
page #14 for N-seris intel CPU. And I also find the same problem
description in https://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/silver-celeron-spec-update.pdf
page #16 for J-series Intel CPU. Seems that they have different
workaround so I can not simply apply XHCI_PME_STUCK_QUIRK to make it
work.

    Anyone can help here?

Chris
