From da6df1c4dcd8e7306bb3cd34c96e19e629b798c2 Mon Sep 17 00:00:00 2001 From: Jim Lin Date: Tue, 8 Aug 2017 08:56:20 -0400 Subject: [PATCH] media: uvcvideo: Fix incorrect timeout for Get Request Section 9.2.6.4 of USB 2.0/3.x specification describes that "device must be able to return the first data packet to host within 500 ms of receipt of the request. For subsequent data packet, if any, the device must be able to return them within 500 ms". This is to fix incorrect timeout and change it from 300 ms to 500 ms to meet the timing specified by specification for Get Request.
