 I prepared the driver to work well with multiple Sensoray 626 and I tested

 I suspect that the analogy interface doesn't play along with the driver but
 I'm not certain about that. Here what's happening.
 I have two s626 cards: s0 and s1. For the sake of conversation let's assume
 that analogy device analogy0 is a0 and so on.
 When I link s0 to a0, unlink, link s1 to a1, unlink everything works fine,
 however. Once more when I link s0 but this time to a1 something goes wrong.
 I get -16 error from a4l_sys_attach() which is

 No such device

 What is the reason of this happening? I do clean everything every time when
 I release s626.
 Here is what I do when I want to open my device:

 a4l_sys_open();
 a4l_sys_attach();
 a4l_open();
 rt_dev_open();
 a4l_fill_desc();

 When I close the s626 I do:

 rt_dev_close();
 a4l_close();
 a4l_sys_detach();
 a4l_sys_close();

 Best regards,

please could you send the driver and the kernel traces for the experiment?
