Can not open device

Post by geoff » Wed Sep 21, 2016 9:48 am

I bought RTL-R820T2, my computer, running Win 7 Professional, says device is working properly, but Sigmira, which works in other respects, repeatedly claims it can not open the device.

Don't forget that all Windows really looks at is whether or not the device responses to the basic USB identification handshakes. It does not look at the internal operation of the device itself.
Therefore all you can really take from Windows telling you the 'device is working properly' is that it can perform the handshake and therefore is likely to pass on the data from your program to the device.
Have you tried some of the RTL-SDR apps such as 'rtl_test' or 'rtl_fm'?

Have you tried a more common program like SDR#?
