yes. Using my other cardreader through pcsc I get

gpg --card-status
Application ID ...: D276000124010200000500000FA00000
Version ..........: 2.0
Manufacturer .....: ZeitControl
Serial number ....: 00000FA0

Language prefs ...: de
Sex ..............: male
URL of public key : [not set]

CA fingerprint 1 .: C485 A6CD 7EC6 6E9E EC33  65F2 70F2 75E4 C32F 6CA5

but I don't want to you that one because

* it needs pcsc
* it the Cheery ST-1044U, which I cannot easily take with me inside the Laptop whereas I can so with 
the omnikey
* I cannot use it but edit my card either

will you tell me?

and meanwhile I could identify it: lsof | grep cmx led to

scdaemon  12382           lorenz    8u      CHR      250,0     0t10     5728 /dev/cmx0

when I kill -9 the scdaemon and retry gpg --card-status, scdaemon gets restarted.

@Peter Lebbing: yes, there is a use-agent line in my ~/.gnupg/gpg.conf
