Dear all,
i am working with 2.6.32 kernel porting on am37xx custom board
here i am facing issues in power saving mode.
after suspend usb and if i resumed using keypad my usb peripherals are
not waking up.
please suggest me if anybody have an idea to fix this issues .
This is definitly a kernel issue.
AFAIK Power Management for ehci-omap is broken. In my case I
desactivated it and just suspend/resume the ehci-hub on PM events.
For 2.6.37 this resolved the issue:
