[opensuse-support] How to wake-up USB ports?
With my primary desktop PC I have the problemsince some years, that some
USB ports do not reliable wake-up after a suspend (suspend to disk) and
resume cycle.

As the result, devices connected to these USB ports do often not work
after resume. The affected USB ports are USB 2.0 ports. With my USB 3.0
PCI extension card the problem does not exists, even with the same
external USB devices.

I tried some tips from the internet but did not found a good solution.

Do you have tips for me?

The kernel error message, if I connect a device (e.g. a USB drive) to a
"sleeping" USB port look like these:

[22674.173306] hub 4-1:1.0: hub_ext_port_status failed (err = -32)
[22674.520974] hub 4-1:1.0: hub_ext_port_status failed (err = -32)
[22674.608968] hub 4-1:1.0: hub_ext_port_status failed (err = -32)

Kernel: 4.16.12-3-default
OS: openSUSE Tumbleweed 20180613 (x86_64)

Greetings,
Björn
