It is indeed not flaky hardware as i wrote earlier. -2 is timeout.
It

is due to a bug in debiread/write
Which lines should I comment in dvb_ca_en50221.c   ???
[root@media2 v4l-dvb]# find . | grep dvb_ca_en50221.c
./linux/drivers/media/dvb/dvb-core/dvb_ca_en50221.c
./v4l/dvb_ca_en50221.c
In dvb_ca_en50221_read_data outcomment this block:
if (status & STATUSREG_RE) {
                ca->slot_info[slot].slot_state =
DVB_CA_SLOTSTATE_LINKINIT;
...
            status = -EIO;
            goto exit;
    }

and this one in dvb_ca_en50221_write_data:
if (status & (STATUSREG_DA | STATUSREG_RE)) {
                status = -EAGAIN;
                goto exitnowrite;
        }
you might also try to outcomment this, also in dvb_ca_en50221_write_data:
if (status & STATUSREG_WE) {
                ca->slot_info[slot].slot_state =
DVB_CA_SLOTSTATE_LINKINIT;
...
            status = -EIO;
            goto exit;
    }

Pleas keep in mind that this just disables some error checks. Actually for
me
...
it solved some troubles.
