need longer timeout with send_feature_report() for libusb under Windows

[oistra-ah]

Hi, could please someone give a hint: is it possible to increase timeout for send_feature_report() on Windows? I have the device, which takes a more than 5 sec sometimes for response. Thanks.

As of this moment that is not possible.

Theoretically if could have been possible, but it would require 2 things:

1. Refactor hid_send_feature_report to switch from HidD_SetFeature to using DeviceIoControl directly;
2. Introduce new API to specify the timeout.

I have the device, which takes a more than 5 sec sometimes for response.

That is astucally weird from system design POV. If that is your device and you know for a fact that by setting a specific feature your device needs to perform a long-going operation, that is advisable not to perform that action directly during the send_feature_report handling, but rather immediately acknowledge that the operation has started, and send the result later in some async matter (e.g. using the interrupt input report).

I any case I don't see much point keeping this ticket opened for now, unless someone volunteers to design the API and implement the change.
