Very few people use it on linux without problems. If you have a USB 1
port it will probably work, otherwise you will likely get the
“insufficient bandwidth” bug.

https://github.com/csete/gqrx/issues/91

There are however no problems with the original Funcube Dongle Pro
(the one without shortwaves and only 96 kHz bandwidth).

I have only usb 2.0 ports on my computer. How likely is that this bug
will
be fixed in the near future?

The funcube pro+ works flawless on my usb 2.0 port. It seems that the
bandwidth problem arises from the usb controller hardware.

I use an ASROCK motherboard with SB7x0/SB8x0/SB9x0 controller in use
with the ohci /ehci kernel drivers. This controller works very well for
me.

The Inc. EJ168 USB 3.0 Host Controller instead does not work. It claims
to have not enough bandwith but for both Funcube devices the ( pro and
the pro+).

Well it is really more of a USB host controller driver problem…
however, bandwidth is always sufficient for the pro +, the problem is
that the driver thinks your device needs more bandwidth than is
available.
However, read the threads on the issues on github; they provide
workarounds. Find out if you can live with these.

If you run linux on your laptop try

lspci -k

and look for USB. Then you can find the controller type.

USB 3 supports higher speed than USB 2 and should offer more bandwidth.
But on my desktop system the dongle only runs on the USB 2 port not on
the USB 3 port. The same happens with the funcube pro that requires
lower bandwidth than the pro +. On my notebook there exists only an USB3
controller Intel 8 Series/C2200 and it works flawless.

Well, I have dell laptop but have no clue which usb controller it has.
Now
I am not sure whether I should by one or not. Anyway, should newer
versions
of usb have higher speed and thus bandwidth.

I have intel 6 series / c200.
could rhel 6 be the prolem here as usually?

Actually, it’s an USB1.1 full speed device (11Mbit/s), and that’s
totally sufficient for 192ksam/s at 16bit (which I guess is the spec).
It does not benefit from USB2 or USB3 hardware.

As the funcube dongle pro+ is not a usb3 device, it does not get
additional bandwidth by being plugged into an usb3 port. I don’t think
it even has the additional pins required to be an usb3 device.
