This interval is OK when we have the= On board / Add on network controllers.=20 In the cases of Network devices exposed via Inband (Virtual USB exposing ne= twork interfaces) when there is a packet read given to USB interfaces and i= t processed in lower level which could not provide the data within the 10 m= s interval and it failed with timeout and communication failed when we perf= orm the HTTP request. Do we have any specific reason to have this as 10 ms? Do we have any max li= mit for this interval value? Thanks, Ramesh
