FCD Pro+ support

[csete]

1. Update documentation to reflect support for FCD Pro+ via https://github.com/dl1ksv/gr-fcdproplus
2. Update device selector with proper sample rate.
3. Test device to see if present gain configuration and defaults are OK.

Is gqrx speaking directly to gr-fcdproplus, or via gr-osmosdr?

EDIT: Found the anser: YES

Indeed. It is safe to assume that all new input sources will come through gr-osmosdr.

Are you able to test FCD Pro+ support? I'd be interested in knowing if it works for you due to issue #91

[asdil12]

I'm afraid I don't have a FCD Pro+ - only a FCD Pro.

[csete]

OK. Btw. FCD Pro support has also been fixed in gr-fcd if you use the latest master branch (after the 3.7 release).

[asdil12]

So gr-osmosdr won't need the additional dependency gr-fcdproplus as it's already included in gnuradio?

[csete]

No, it's a little more complicated.
The Pro and Pro+ are very different devices from an API point of view, much more different than the name suggests, and they need two different drivers.

The gr-fcd block supports the FCD Pro and is included with gnuradio, thus gr-osmosdr will support it without any additional packages. However, for FCD Pro+ support one needs to install the gr-fcdproplus package, which is external to gnuradio. So, if you want support for FCD Pro+ the installation order is:

1. GNU Radio
2. gr-fcdproplus
3. gr-osmosdr

If you omit step 2 then gr-osmosdr will support FCD Pro but not the Pro+.

Does this make it more clear?

After finally getting gnuradio-3.7 installed on Fedora 19 last night, I give the new FCD++ support a try and it's working very well so far. Great work!

Thanks for the feedback @fsphil
Can you tell me which kernel version, USB port type and USB driver you are using, i.e. when you plug the dongle in and type "dmesg" it should tell you whether it is using xhci, ehci or ohci. This info would be interesting because of issue #91

[fsphil]

On the laptop:

Kernel 3.9.10-100.fc17.i686
It's a USB2 port, using the uhci_hcd driver:

Thanks for the info. I think that's the USB 1 driver, so you are lucky :-)
