[Solved] No USB Keyboard and USB Mouse after suspend to ram

[dontknow]

Hello.

Have many unsuccessful experiment hours behind me, and it doesn't run. Question therefore here.

I recently installed gentoo, kernel: gentoo-sources, uses openrc and kde 4. everything up-to-date.
To have suspend to ram available in kde i installed upower-pm-utils.
i followed the instructions on
https://wiki.gentoo.org/wiki/Suspend_and_hibernate
https://wiki.gentoo.org/wiki/Power_management/Guide
and many more..
all required settings in kernel are set, compiled and restarted.

Now if i go to suspend to ram via kde (or pm-suspend) it works - fine.
I can wake up via keyboard - fine. kde shows up.
BUT my usb keyboard and usb mouse (both on a monitor usb hub) are not working anymore.
I must reset my computer manually.
Strange: if i press a key after the wakeup then the laser on the bottom of the mouse flashes short.


if i google then it shows me solutions like here: http://hamwaves.com/usb.autosuspend/en/
but it doesn"t work for me.

Have anyone another ideas / suggestions?

I forgot to enable USB3 support in the kernel.

cd /usr/src/linux
make menuconfig
Device Driver --> USB Support --> xHCI HCD (USB 3.0) support

make && make install

after restart pm-suspend / kde suspend works fine.
