I have tested again today, box works OK with CCcam and reads Conax card. But since i have NDS card here i need and must use OScam as card reader.
As soon as i start OScam the conax card gives this output


14:42:41 5CxxxC0 r ERROR: 0 characters found in ATR
14:42:41 5xxxC0 r Error activating card.
14:42:42 5xxxC0 r ERROR in IO_Serial_WaitToRead: fd is in error fds, (errno=0 Success)
14:42:42 5xxxC0 r ERROR: 0 characters found in ATR
14:42:42 5xxxC0 r Error activating card.
14:42:42 5CE9C0 r card initializing error

So OScam does not read any card with either Mara M9 or Venton Unibox HD3 that i have.
the strangest thing is that with Ultimo this works perfectly , same CCcam version, same OSCAM VERSION, same Image,

I do not know if this is a problem with drivers or OScam for this boxes


thanks for the help so far
