Would you please test this with 2.6.22-rc4? If it is still broken, would it be possible to do bisect search for the offending patch? Thanks. I have checked with 2.6.22-rc4, and the bug still is there, but I am sorry to say that I neither have the time nor the experience to do any further work on it. Some additional information, I found out since but forgot to post: The bug only occurs, when the reader is accessed from a 32bit application on my 64bit host. If 64bit applications access the smartcard reader, the bug does not show. I've got the same problem, cardreader kobil kaan pro 2.09r, last working kernel 2.19-r5. I 'd like to help fixing this this problem. Claudius, is your cardreader still failing with current 2.6.23+? I'd say latest git is always best one to try, making sure we are not chasing a bug that has been fixed upstream. If it does, maybe you could try the git-bisect to find the bad commit.
