Hi, I hope this is the right place for posting this.

I have the above TV tuner / capture device which has been working well
in Ubuntu 16.04. I've decided to update the OS to Ubuntu 20.04 with a
fresh install on a different disk and haven't been able to get this
device working.

Ubuntu 21.04, 18.04 have also been tested with the same results. On a
fresh install of 16.04 this device works well.

It seems something has changed between 16.04 (kernel 4.15.0-142) and
18.04 (kernel 5.4.0-42).

In /etc/modprobe.d/dvb.conf
# Sony Play TV
options dvb-usb-dib0700 adapter_nr=5,6 force_lna_activation=1

This has been tested with different variations of the above without success.

When using w_scan with a file manager open I've noticed if scanning
adapter6 I could see the folder named adapter5 disappear. I then
opened up the adapter6 folder and two of the four files had
disappeared. When the scan finished the files/folder reappeared,
however the device then became unusable.

'modinfo dvb_usb_dib0700 | grep depends' yields the following

For Ubuntu 18.04
depends:
dib7000m,dib9000,dibx000_common,dvb-usb,dib0090,dib0070,dib3000mc,rc-core

For Ubuntu 16.04
depends:        dib7000m,dvb-usb,dib0090,dib0070,dib3000mc,rc-core

So something has changed in the driver?

Please let me know if any further information is required to help fix this.
Thanks
Andrew
