Ah, no. According to Absolute FreeBSD, 2nd ed, which I have in front of me,
newfs invoked by sysinstall, which I used to create the slice and partition
it (p 241).

Anyway, I now try running newfs in terminal, but it throws up some errrors:

# newfs /dev/da0s1c

Invalid argument

I tried it several times; the errors seem kinda random, since they vary
each time I run the command.

Could it be that the chipset of this USB device, JMicron, is not entirely
supported by FreeBSD? The reason I ask is because this appears to be an
issue under Linux; cf, http://www.qbik.ch/usb/devices/showdev.php?id=3751

Yes, I am well aware it is a different OS (!); I only mention it in case
there is overlap in the codebase for this particular chipset.
