Cannot access RTL device

Post by butchalline » Sat Aug 08, 2020 9:31 pm

SDR# was working in the morning, came back in the afternoon and it was frozen.
Closed SDR# and restarted but got "Error: Cannot access RTL device"
Changed serial ports, restarted PC and still got error.
Read the quick start guide, used Zadig to reinstall driver and still get error.

Using Win 10 64bit, RTL-SDR v.3, SDR# ver., Source: RTL-SDR(USB)

Checked win updates and there were no recent updates. Looked at device manager and could not see SDR, but maybe it shows up elsewhere?

SDR is warm as expected and tests at 80mA @ 5.00VDC.


Any and all help appreciated, thanks.

Update: Used the above set up on another PC, and everything works as expected.

Found the following info in Device manager on the non-working PC:
