Well, you know what to do. Edit your dumped asl file (though I am not sure if
simply adding the code shown in this attachment will work for you).

Because at first I didn't know how to fix compiler errors in the asl file that
was decompiled from the original aml file, I loaded a distro of linux and after
dumping the DSDT tables again, noticed that errors were easier to fix this
time. I fixed the errors, then applied the changes that were described in the
previous post, and used the resulting aml file to override the memory tables on
FreeBSD 11 and 10.x. However, then I decided to struggle with fixing the errors
that I got after compiling the original asl file on FreeBSD. I eventually fixed
them, but the changes that I described in the previous post didn't make
/dev/psm0 come to life this time. So, I applied the code from this site
http://www.tonymacx86.com/threads/ps2-not-working-after-installing-dsdt.53498
and this time /dev/psm0 came to life. I have no idea why the asl file that I
got on Linux was different from the one that I got on FreeBSD. Both OSes used
the same version of iasl to decompile the aml file.

I succeeded in getting this touchpad recognized as a basic PS/2 device. I
dumped the DSDT tables from memory with the acpidump command. In the asl file,
I edited the PS2K section replacing all the "Return" lines with the lines that
say the same thing: Return ("") . I compiled the code and made loader.conf
aware of the resulting aml file. Now /dev/psm0 gets created and I can finally
use the touchpad on FreeBSD 10.x or FreeBSD 11.

Bug ID: 209473
   Summary: There is no /dev/psm0 device for my synaptics touchpad
when I load FreeBSD 10.3-RELEASE
   Product: Base System
   Version: 10.3-RELEASE
  Hardware: amd64
OS: Any
Status: New
  Severity: Affects Only Me
  Priority: ---
 Component: misc
  Assignee: freebsd-bugs@FreeBSD.org
  Reporter: oleglelc...@gmail.com
CC: freebsd-am...@freebsd.org
CC: freebsd-am...@freebsd.org

I have a strange issue. I own this particular laptop:
http://www.newegg.com/Product/Product.aspx?Item=N82E16834298945 and FreeBSD
10.3-STABLE, 11-CURRENT and 10.3-RELEASE don't recognize this touchpad. It's
not even recognizable as a generic PS/2 mouse. No matter how many suggestions I
followed (such as putting hw.psm.synaptics_support="1" in loader.conf or
modifying xorg.conf), this touchpad remains completely undetectable on either X
or the console by the versions of FreeBSD that I mentioned above. These
versions of FreeBSD never created [file]/dev/psm0[/file] device in the /dev
directory. However, FreeBSD 9.3-RELEASE did detect this touchpad as a generic
PS/2 mouse! When I typed [code] dmesg | grep psm[/code] after loading
9.3-RELEASE, I got this: [code]psm0:  irq 12 on atkbdc0
psm0: [GIANT-LOCKED]
psm0: model Generic PS/2 mouse, device ID 0[/code] . Then I am able to use the
touchpad after executing the moused command. So, please explain to me what I
can do to get rid of this issue on 11-CURRENT or 10.3-STABLE. All I want is for
one of these versions to recognize this touchpad as a generic PS/2 mouse. The
OpenBSD kernel ver. 5.9 is able to recognize this touchpad as a Synaptics
model. I can use it when I load X on OpenBSD.
