From 95c21c4158cc8b5a2920ccbe989b17b6f955d976 Mon Sep 17 00:00:00 2001 From: tvboxspy Date: Sun, 11 Sep 2011 19:26:50 -0300 Subject: [PATCH] [media] [1/2,ver,1.89] DM04/QQBOX Interupt Urb and Timing changes Reduce buffer size of Interupt urb to 128 bytes and polling interval to 8. The devices buffer appears to only handle a maxium of 40 bytes. If the buffer is full a slowing effect is noticed causing occasionnal dropped streaming packets.
