chipcard2-tools works only once after installation

After several days of trying and failing i managed to get 
chipcard2-tools and qbankmanager to run on my debian box, thanks to 
Thomas Viehmann's hint.

I'm using a cyberjack2 reader for my ddv1- card and had a successful
qbankmanager session - right after setting up libchipcard2-tools. 
Transmissions, reports and so on worked beautifully.

After a reboot of the system chipcard2-tools can't access the card
reader any more. I had the same result after my first attempt to set up 
libchipcard2-tools
	
	chipcard-tool list

reports the reader correctly, but

	chipcard-tool check

gives this error:

	tim@brocken:~$ chipcard-tool check
	  Readers:
	  - auto1-cyberjack2 (cyberjack2, port 0): error
	Event log:
	13:22:40 Reader listing
	13:22:44 Reader error (Unknow error code)

(same as root)

chipcardd2 is running and configured as typ=local with socket path. No
changes to that since my homebanking session.The socket file is deleted
cleanly when the daemon shuts down.
A Reiner-SCT script to read "Geldkarte" amounts from the card still
works, so the reader seems to be half-way alright.

I tried a

	strace chipcard-tool check

which of course whacked me with output, so i don't post that here except
for a small excerpt, see end of mail.
After all, i'm not sure what chipcardrd is good for. Do i need that?

Thanks for any hints!

(lines beginning with gettimeofday are repeated dozens of times in the
output)
