If this is not a typo and you actually got a -1 and not a 1 then the
error is not EPERM (permission denied), rather it looks like a problem
in the device driver code. The u.u_error structure member is not being
set to anything intelligible, it is simply all ones which means it is
probably uninitialized. Someone at ISC who has the driver code should
take a look at the code and figure out what's wrong. Have you tried to
call their support?

Good luck,
