OP25 OP25 persistent error

[ewh01]

I am running boatbod OP25, starting via ./rx.py. It will run for a while, but at random times it will lock up, each time the stderr file shows the error below

cb transfer status: 5, canceling...
rtlsdr_read_async returned with -5

Traceback (most recent call last):

Does anyone know what is going on and/or how to fix this?

Thanks

It looks like a loss of USB connectivity with your SDR dongle. Check that your SDR's USB connections are mechanically and electrically secure and don't overlook the SDR itself or a faulty USB hub or extension cable(s) if used.

OK, I'll try a different USB port.

It just happened again, and I got the following from running tail -f

Those are definitely errors that you see when the rtl driver looses contact with the hardware device. I've seen it happen under several different conditions:
- RPI with inadequate power supply (low voltage)
- RTL with intermittent USB connector (i.e. a physical issue)
- RTL device going bad (i.e. an electrical issue)

Looks like it's time for a new dongle!!

Thanks folks!!
