I read carefully through the PR 231076 (and deleted freebsd-current from
the mail thread). The PR does not match my problem.

I think, we should isolate the problem from PCSC and focus (first) on the
question why are calls to usbconfig(8) are not answered anymore
*without* any kind of PCSC software being involved as I wrote in the
originating email of this thread. Here it is again in case in got lost
while talking about PCSC:

If it would help, I could file a new separate PR with the dates below.

I updated my amd64 laptop Acer C720 from r314251 to r342378. ...

.... To separate the problem from GnuPG and it's software stack, I have here some
small tests with usbconfig(8). First usbconfig reads fine the bus, but then
it takes 3-5 minutes to get any results, see below.

Please, what can I check or enable to get additional logs for the problem.

...

Ther first 3 commands usbconfig(8) are answered immediately, then it
takes minutes to get any response. Why?
