RTL v4 dongle, and linux?

[E B]

Hello

SparkSDR (2.0.992.0) is not detecting my dongle (a genuine product bought from https://www.technofix.uk ).

I did search the email archives but failed to find something suitable; please can someone point me in the right direction? I am running linux mint and I can  identify the dongle:

$ lsusb

Bus 001 Device 005: ID 04a0:9003 Digital Equipment Corp. USB Keyboard

and things like rtl_433 work fine. However, sparkSDR  doesn't recognise it; I have said to "Use RTL driver" and/or "Use SoapySDR driver" to no avail.

I have previously used SparkSDR with an SDRPlay RSP1 but now I have changed to the RTL dongle, using the SDRPlay elsewhere (RPi4 using an openwebRx+ image).

I'd like to get my RTL dongle working on my Linux Mint box.  Is it possible and if so, how should I approach it, please?
