I've compiled osmo-fl2k with libusb-1.0.22-1 and this happens when I
tried to start fl2k_test:
feanor at silmaril ~> fl2k_test -s 162e6
Using 6 zero-copy buffers
libusb: error [op_dev_mem_alloc] alloc dev mem failed errno 12
Failed to allocate zero-copy buffer for transfer 4
Reporting PPM error measurement every 10 seconds...
Press ^C after a few minutes.
real sample rate: 15372775 current PPM: -905106 cumulative PPM: -905106
then when I try to connect red and ground output to oscilloscope,
there is no output at all, even if I use fl2k_fm
