Sorry, I can't answer your question.
Just another question to you: is your USB chipset on the motherboard
a "VIA 83C572" ?

I have equivalent problems for a USB storage device with 4.10-Stable.
I can mount (and then I can access the USB filesystem), but the whole system
freezes when I umount the device. After googling a bit on this issue, I think
it is because of the USB chipset on the motherboard, which is a VIA 83C572.

I tried this USB storage toy on another FreeBSD PC with a Intel 82801BA/BAM
USB chipset, and there it works flawlessly.

So far, I haven't had much luck sharing the problem with the mailing list.
(I heard of one more person with the same problem, though).
