9. A non-transitory computer-readable medium comprising instructions that, when executed, cause programmable circuitry to at least:
determine a bit rate of a signal at a universal serial bus port of a media device;
if the bit rate exceeds a threshold, determine the media device is involved in a data transfer; and
if the bit rate does not exceed the threshold, determine the media device is not involved in the data transfer.
10. The non-transitory computer-readable medium of claim 9 , wherein the instructions are to cause the programmable circuitry to determine the bit rate of the signal by determining a number of bits processed in the signal during a time interval.
11. The non-transitory computer-readable medium of claim 9 , wherein the instructions are to cause the programmable circuitry to:
generate transfer activity data indicative of whether the media device is involved in the data transfer or not involved in the data transfer; and
timestamp the transfer activity data.
12. The non-transitory computer-readable medium of claim 11 , wherein the instructions are to cause the programmable circuitry to transmit the timestamped transfer activity data.
13. The non-transitory computer-readable medium of claim 9 , wherein the instructions are to cause the programmable circuitry to collect data from the signal.
14. The non-transitory computer-readable medium of claim 13 , further wherein the instructions are to cause the programmable circuitry to timestamp the data.
15. The non-transitory computer-readable medium of claim 14 , wherein the instructions are to cause the programmable circuitry to transmit the data.
16. The non-transitory computer-readable medium of claim 13 , wherein the instructions are to cause the programmable circuitry to collect the data after it is determined that the media device is involved in the data transfer.
17. A method to monitor a media device comprising:
obtaining, by executing an instruction with a processor, a first signal and a second signal at a universal serial bus port of the media device;
determining, by executing an instruction with the processor, whether a first bit rate of the first signal exceeds a threshold and whether a second bit rate of the second signal exceeds the threshold;
when the first bit rate exceeds the threshold, determining, by executing an instruction with the processor, the media device is involved in a data transfer; and
when the second bit rate does not exceed the threshold, determining, by executing an instruction with the processor, the media device is not involved in the data transfer.
18. The method of claim 17 , further including:
after the determination that the media device is involved in the data transfer, crediting media as having been accessed; and
after the determination that the media device is not involved in the data transfer, not crediting the media as having been accessed.
19. The method of claim 17 , wherein the first bit rate of the first signal is based on a quantity of bits represented in the first signal during a time interval.
20. The method of claim 17 , further including:
generating transfer activity data indicative of whether the media device is involved in the data transfer; and
timestamping the transfer activity data.
21. The method of claim 20 , further including transmitting the timestamped transfer activity data.
22. The method of claim 17 , further including collecting data from the first signal.
23. The method of claim 22 , further including timestamping the data.
