r342378: usbconfig takes 3-5 minutes to read the bus

I updated my amd64 laptop Acer C720 from r314251 to r342378. The OpenPGP Card 
HID Global OMNIKEY 6121 was working in r314251 nicely and after withdraw and
re-insert GnuPG was just asking for the PIN again and access to the ciphered
material or signing keys was fine.

Now with r342378, it works only after boot but not after withdraw/re-insert
anymore. 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.

Thanks
