I did take a long look in the BIOS, but i have not seen anything interesting as far as any kind of USB settings goes.
When I boot with the external mouse plugged in and then disconnect the external mouse, the trackpad still works. That is because when I boot the system with the external USB mouse connected, the system creates both /dev/ums0 and /dev/ums1 (which you'll see from the output of dmesg from 2 verbose boots below). Moused then runs on both device nodes. When I disconnect the external device, /dev/ums0 is removed while /dev/ums1 remains. Normally, when I boot the system without the external mouse, /dev/ums* is not created at all. /dev/ums* only appears if I connect the external device.

One thing that puzzles me is why the following message appears during boot (it might be unrelated):
"psm0: unable to allocate IRQ"

Originally I tried to post the output of dmesg from the 2 verbose boots here, but the message got rejected because of its size. Therefore, output from dmesg is available from the following 2 links.
Output of the verbose boot messages without the external mouse:
https://www.dropbox.com/s/ukpoyg6rsl3jjgd/dmesg_without_external_usb.txt?dl=0

Now, I gave the command "shutdown -p now" (power off the system) and then plugged in the external USB mouse. After that I ran a new verbose boot:
