If the mouse is connected to PS/2 port, the following device flags may
help.
psm(4):
bit 13 HOOKRESUME
The built-in PS/2 pointing device of some laptop computers is
somehow not operable immediately after the system `resumes' from
the power saving mode, though it will eventually become available.
There are reports that stimulating the device by performing I/O
will help waking up the device quickly. This flag will enable a
piece of code in the psm driver to hook the `resume' event and
exercise some harmless I/O operations on the device.
bit 14 INITAFTERSUSPEND
This flag adds more drastic action for the above problem. It will
cause the psm driver to reset and re-initialize the pointing
device after the `resume' event. It has no effect unless the
HOOKRESUME flag is set as well.
I always use hint.psm.0.flags="0x6000" in /boot/loader.conf, i.e.,
turn on both HOOKRESUME and INITAFTERSUSPEND, to work around similar
problem on different laptop.
Can you please report other problems in the appropriate ML?
em -> freebsd-net@
usb -> freebsd-usb@
acpi_ec -> freebsd-acpi@
BTW, USB stack issue is known problem AFAIK.
