NAK quits after 3 attempts on control transfers?

[ulao]

Is there a place in the code where we control the NAK timeout or count? When I disable transfers on my device for a moment the host seems to only try tree more times. After this, the hid_send_feature_report returns a -1. It should continue for a bit longer.

That is what the OS is doing. You can not change that.
