USB GPS conflict with two serialized USB SDR's
« on: June 22, 2021, 06:53:56 PM »
Looking for help...  I have an RPI running PiAware & RBFeeder. I have two SDR's serialized for 978 and 1090.

Output from rtl_test -t

Found 2 device(s):
  0:  Realtek, RTL2832U, SN: 00000978
  1:  Realtek, RTL2832U, SN: 00001090

Using device 0: Generic RTL2832U
usb_claim_interface error -6
Failed to open rtlsdr device #0.

My problem is when I plug my USB GPS in I lose USB 0 SDR because the GPS takes it. 

My GPSD config is:
# Default settings for the gpsd init script and the hotplug wrapper.

# Start the gpsd daemon automatically at boot time

# Use USB hotplugging to add new USB devices automatically to the daemon

# Devices gpsd should collect to at boot time.
# They need to be read/writeable, either by user gpsd or the group dialout.

# Other options you want to pass to gpsd

I'm not familiar with USB initialization and assignment.  Please help if you can.

Thanks,  Ron

P.S. The reason I want the GPS working is I will be going mobile in my motorhome.
