The powersave modes do not work with USB devices (tested with a
RTW8822CU) properly. With powersave modes enabled the driver issues
messages like:
rtw_8822cu 1-1:1.2: firmware failed to leave lps state
rtw_8822cu 1-1:1.2: timed out to flush queue 3
Also ping round trip times increase significantly from 1..2ms to
10..200ms.
Until this has been resolved disable the powersave modes for USB
devices.
