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.
