Dear Experts,
My system: custom board, dm8148, dvrrdk 3.50.
Except USB test mode, I have to measure USB suspend/resume waveform in DM8148.
I try ( https://bbs.archlinux.org/viewtopic.php?id=95659 )
echo "0" > "/sys/bus/usb/devices/$port/power/autosuspend"
echo "auto" > "/sys/bus/usb/devices/$port/power/level", but seems not work.
Does anyone can tell us how to achieve USB controller to suspend and resume in DM8148 ?!
thx ~
HB
