Don't bother. "Add support for USB-based ExpressCard devices to any USB
equipped computer" is actually a lot more explicit than many of those
cards bother telling, and it means that they work fine for WWAN cards
(UMTS Modem and such), Smartcard readers and reasonably cheap (all but
the fastest) flash device reader cards. An Expresscard slot provides
both a PCIx lane and a USB connection. This adapter will only provide
the USB connection. That's not sufficient for a Firewire adapter.

I've been poking around on Amazon. The consensus of reviewers seems to
that USB-C to Firewire adapters don't work and simply cannot
work. Including a review by an electrical engineer.
I found this USB<>ExpressCard adaptor:

I have a System76 laptop. There's no
Expresscard port on it.
On their current baseline "Lemur" model I see
Expansion: USB 3.1 Type-C, USB 3.0 Type-A, USB 2.0 Type-A, SD Card Reader
That's sort-of "ugh" for connecting Firewire devices. Concerning the
bandwidth, I think you'd need USB 3 (USB 2.0 nominally has 480mbps over
Firewire's 400mbps but reserves less for synchronous transfers and there
are other problems IIRC). I don't know about reliable adapters, but I
haven't looked.
I've got to try some. The only other option I would have would be to
use it on one of my desktop systems, which aren't exactly very
portable! IIRC, the original poster had a Firewire ExpressCard
and was looking
for a laptop with an ExpressCard port. Maybe this would work for them?
Nope.
