This explanation makes no sense. 3ft is practically the shortest USB cable anyone would use. Equally, assuming a compliant correctly functioning cable, cable length doesn't affect the time it takes to execute transactions.

Is the issue more that if a low quality cable is used, then there are lots of transfer errors, and the time taken for retries is large? If so, there's not much guarantee that a larger timeout would help in general, since there's no guarantee of any upper bound on the time it takes for a packet not to get corrupted in this case. Still, I suppose it's fine to increase the timeout to account for when it accidentally works.

In summary: a commit description that more accurately represents the problem being solved is required.
