Problem accessing 'qvm-usb'-associated SmartCard reader as non-root user

[Johannes Graumann]

Hello,

As I am transitioning all aspects of my evolving setup into qubes, I'm
stuck at making a SCR3310 smartcard reader (used to store my gpg secret
key) usable in an AppVM based on fedora25-minimal (had tu upgrade, as
evolution-functionality I require is not in fedora24) and dedicated to
run Evolution as the email/group ware client.

1) I have sys-usb running
2) qvm-usb on dom0 shows the reader and I can connect it to the appvm
using the same tool.
3) ROOT on the appvm can issue gpg2 --card-status just fine, but I have
so far failed to make the reader accessible to the qubes-used user
'user'.

There's neither a debianish plugdev nor an usb group to add the user
to.

I have provided an appropriate udev rule in the template vm that should
associate the device with the group 'user', but that doesn't work
either ...

Furhter tips? Any insight into where I err?

As noone here chimed in, I took this to stackexchange (http://stackover
flow.com/q/43770378/2103880), where I report details of the problem.

Any insight?
