One alternative is to change rtlsdr-device-index in configuration, as shown in my post above.
Another alternative is to change serial number of ProStick from 00001000 to 00000001, and Generic dongle from 00000001 to 00000000.
| Dongle | Displayed As | Default Serial | Modified Serial |
|---|---|---|---|
| Generic | RTL2838UHIDIR | 00000001 | 00000000 |
| ProStick | RTL2832U | 00001000 | 00000001 |
