That's right. You should see a line like:
Bus 003 Device 006: ID 04d8:fb31 Microchip Technology, Inc. FUNcube
Dongle V2.0
The bus and device numbers will probably be different, but the rest of
the line starting with ID should be the same.
Note that while the data path of the device looks just like an audio
device, there's also a control interface that requires a driver and library.

But you have to set the correct PATH callsigns in your APRS radio.
That would be NA1SS,PSAT for a dual hop.
NA1SS would hear it first and then transmit it via the path of PSAT which
then (if it heard it amongst all the other QRM on the channel) would then
digi eat it too.
Doing the dual hops in this direction (assuming they can see each other
(rare) is because the chance of the ISS hearing the weak 0.25W XMTR form
PSAT is very small compared to PSAT hearing the 10W signal from ISS. So a
dual hop path in this direction has a 16 dB better chance than one
attempted in the opposite direction. And that is Huge.

Hello there,
I would like to know if there is anybody to uses Linux to decode BY70-2
And can help me how to do.
I have all set ( It seems ), I can decode the satellite but I do not get any
incoming data into the Proxy.
I have downgrade the Tornado how it says in the Doc file but still no
success.
Anybody able to help me may be off the list?
Thanks in advance

Might be a USB Host scheduler bug, indicating that something wanted to
talk to a USB device, but the kernel thought it didn't have enough of
the 12 Mbit/sec (or 480 Mbit/sec in USB2.0 HS, or something GBit/sec in
SuperSpeed, etc.) bus to satisfy the request.
urb stands for "USB Request Block", which is how some kernel device
driver sends requests, to read/write the actual USB device, within the
kernel.
> [ 90.010218] usb 1-1.2: 1:1: cannot get freq at ep 0x81
This message originates in sound/usb/clock.c, apparently trying to read
the sample rate from endpoint 0x01 (the high bit set denotes IN to
Host). From the comment:
> return 0; /* some devices don't support reading */
However, this appears to be non-fatal.
I'd suggest trying another version of Linux, if possible.
The FCDP+ works on FreeBSD, with one annoying HID quirk that I've been
trying to get the FCD programmer to fix for a few years now. I need to
email him directly again and see if he can update the firmware.

Ah ha! The driver wasn't able to reserve enough bandwidth on the USB hub
for the 192 kb/s 16-bit "stereo" audio stream. Try moving it to another
USB port. Most computers have several USB hubs, and it's not obvious how
the various sockets connect to them. Try temporarily disconnecting any
other USB audio interfaces you might have.

This got me thinking and I tried it again on the laptop that has a USB 3.0
port. I tried it directly in that port (no hub), although I DID use a USB
3.0 extension cable. It works!
So the problem (at least on this laptop), is that it needed the USB 3.0
port? I thought that it was supposed to work on any USB port? *shrug*
It doesn't appear to work on the cheapo amazon USB hub that is plugged
into a different USB port (but I can't say for sure that that port is USB
3.0 or not, though).
Thanks for the tips! Regardless of what was wrong, it's working now!

Phil, I'm sure you've probably seen my other response, but at least you are
putting a technical explanation behind it. Yep, while it still doesn't
work AT ALL on my small "backup" computer, I plugged it directly into the
USB 3.0 port on my primary shack computer and it is now working. Thanks
everyone for giving me some time to help me figure this one out!

I find all the dongles, including FCDPP, to work best with external powered
USB hubs. When in doubt, try that. Too many flakey results otherwise.

I'm preparing to sell a couple of items that would be of interest to
satellite operators:
Kenwood TH-D7A(G) full-duplex VHF/UHF FM hand-held radio equipped with
a built-in TNC (1200/9600) and APRS capability. Also, 200 memories
(100 each band), CTCSS, and backlit keys. RF output is 2 to 6 watts,
depending on type of battery pack or external DC supply. This comes
with original box and manuals, "rubber duck" antenna, SMA to BNC
antenna adapter, SMC-34 speaker-mic, wall-wart charger, PB-39h 9.6v
1450 mAh battery with belt clip.
Control box ONLY (no motor) for a 24vac Yaesu G-550 elevation rotator.
Note, this box is only for the elevation rotor, not to be confused
with the G-5500 Az/El system. This elevation-only control box is brand
new, never used except to test. No manual or other documentation
included, but available online.
E-mail me off list for prices, photos, etc.

I agree, the Raspberry Pi is especially notorious for not being able to
power USB devices.
But I don't think that's the case here. The message about not being able
to allocate enough USB bandwidth is the key.
