Dongle hangs detection #72

Description

@testuser7

I have RTL2838 based dongle that hangs very often. rtl_433 detects this and exits with the message: Async read stalled, exiting!
rtl_sdr waits for a response from the dongle and does not exit:

rtl_sdr -f 868.95M -s 1.6M -
Found 1 device(s):
  0:  astrometadvbt2, dvbt2, SN: 

Using device 0: Astrometa DVB-T/DVB-T2
Found Rafael Micro R828D tuner
[R82XX] PLL not locked!
Sampling at 1600000 S/s.
Tuned to 868950000 Hz.
Tuner gain set to automatic.
Reading samples in async mode...

Is there a chance to implement a similar functionality?

Usbreset application is able to properly reset dongle: https://marc.info/?l=linux-usb&m=121459435621262&w=2
Is it possible to implement usbreset code inside rtl_sdr?
