I had thought that my SDRplay RSP2 was dead because none of my computers would recognise it. But I noticed that it was still drawing current from the USB port when attached and 50 mA seemed reasonable.
I got it to work under CubicSDR somehow, but it was not reliable. Luckily at some stage it was working (I was listening to a Classic FM broadcast) and I accidentally tapped the RSP2 and the dulcet sounds of the orchestra turned into a loud buzzing noise. I realised that it was a hardware problem and I tried to recover and nothing would work until I tried an old USB cable. The RSP2 works fine with this cable but not with any other!
Maybe I’ve lived a sheltered life but I don’t remember any device having a dodgy USB type-B socket. Micro- and mini-USB fails are common, but type-B?
Anyway, I’m happy now because I can monitor my VHF Q65 transmissions using the SDRplay.
