I even have that page bookmarked, but I forgot to look there :-(

The card claims to support either 3.3V or 5V, but it doesn't work
in slot 1 but does in slot 2.  I bet it's expecting the higher
bus speed or bus width; its documentation mentions nothing about
either.

... for small values of "work", anyway.  It now shows up with
reasonable-looking entries in pcidump and dmesg.  However,
OpenBSD still doesn't see the USB drive I plugged in for
test purposes.

I get these pcidump entries that were not there before:

uhub0: device problem, disabling port 4

(about 12 seconds between each pair of tsleep complaints)
The above is with OpenBSD 6.4, which is what I had installed.
Booting OpenBSD 7.0 off a CD, I see the same except that
the "ehci_sync_hc" complaints aren't printed --- but there's
more or less the same long delays before the "disabling port"
messages.

Interestingly, the above is with the USB drive plugged into
the card's port 3.  I moved it to port 1, and instead got
complaints about disabling ports 1 and 4.  I moved it to
port 4, and got only the complaint about port 4.  Maybe this
is more about incompatibility with the drive (it's an ancient
LaCie that I wasn't using for anything) than the card?

Anyway, many thanks for your help!
