some more reading, and it seems that indeed open fires up a startread,
so that select should work. In my case, i just went the old fashion way,
sigalarm/read, but it seems that nothing is being read by the driver :-(
assuming that uco/ulpcom works - the problem must be in the way this
smartcard reader works.
