Turns out it was mounted on /dev/bus/usb/001/005:
crw-rw-r-- 1 root pcscd 189, 4 Feb 14 19:13 005

The access rights seem ok to me - the smart card daemon pcscd has full
rights to the device. Does anyone have other ideas I could test out?

A more directly gnupg related matter also came to light - after the
card reading fails (see my earlier examples) and the scdaemon goes
belly up it seems not to die peacefully: When I remove the Crypto Stick
my syslog starts filling up with thousands identical entries as follows:

...Ad infinitum

So I have to restart the machine to avoid bloating up the syslog. 

The same does not happen if I only plug in the stick and then remove it,
without running gpg2, the only entries (for the disconnect) are as
follows:

Feb 14 19:34:44 Sibelius kernel: [  206.379447] usb 1-1.2: >USB
disconnect, device number 5 Feb 14 19:34:44 Sibelius pcscd:
ccid_usb.c:660:WriteUSB() write failed (1/5): -4 No such device
