Hello, Steve. I tried the fix you suggested the other day, but I still end
up with the same error as before.
I thought it'd help if I show what exactly I'm seeing in my console output
when I try to run both dump978 & dump1090 at the same time.

can't seem to stop rtl_sdr from allocating too many zero-copy buffers
and preventing both programs from running simultaneously (I'd like to
cut down from 15). I've been through librtlsdr.c and rtl_adsb.c with the
hope of manually changing some variable that will let me accomplish this
to no avail.
Just increase the usbfs memory limit, the default is only 16MB.
Either write the new size, or completely disable the limit with:
echo 0 > /sys/module/usbcore/parameters/usbfs_memory_mb
