Hi,

trying to provide a bit more information:

Using -vvv doesn't give any more clues:

The arguments seem plausible to me, but the ioctl still fails with EINVAL.

What might be more interesting is the kernel message produced by the
failed attempt:

| [42607.855196] b2c2_flexcop_pci 0000:09:00.0: DVB: adapter 0 frontend
0 frequency 12551500 out of range (950000..2150000)

This frequency range doesn't look like DVB-S at all...

Regards,
