Problems with RTL-2832

[radiod42]

I have been running 3 RTL SDRs and an AirSpy R2 for several months. I had one RTL recently error and stop. Reinstalled drivers and all. Not sure what the issue is all of a sudden. Help appreciated! Win 10

You might try plugging the dongle into another USB port, but beyond that I don't have any ideas.

In addition to Denny's suggestion to trying a different port (or USB hub if you're using one), you should verify that the eeprom data hasn't corrupted itself. You can use a tool like rtl_eeprom.exe.
