I'm confused by this sentence. Are you trying to get the system to come out of S3 by using your mouse (e.g. clicking a mouse button)? And sometimes it doesn't work? You're missing a bunch of details in this bug report as well: 1. What system are you running under? 2. What does `sudo lspci -vvv` show? 3. What kernel version are you running? 4. Does the problem with remote wakeup only occur with your mouse or does it occur with other USB device classes? 5. Does the issue only occur with one particular mouse, or with all your mice? 6. Do the effected mice work fine under a different xHCI host or EHCI host? > Then I reset the port > which current status is connected in PORTSC during pci resume process > in host controller driver (xHCI), this issue doesn't happen.

So resetting the port after resume from S3 allows the remote wakeup to correctly propagate up during the second S3? > So have you any ideas to > distinguish that the device class is mouse which attached on port in > host controller drivers? You're proposing a solution before clearly defining the problem. Please explain to us, in detail, what the problem is, with step-by-step instructions on how to reproduce it.
