+Subject: [PATCH] MUSB: BULK request on different available endpoints
+Date: 	Tue,  7 Oct 2008 11:12:24 +0530
+
+Fixes co-working issue of usb serial device with usb/net devices while
+oter endpoints are free and can be used.This patch implements the policy
+that if endpoint resources are available then different BULK request goes
+to different endpoint otherwise they are multiplexed to one reserved
+endpoint as currently done.
+
+NAK limit scheme has to be added for multiplexed BULK request scenario
+to avoid endpoint starvation due to usb/net devices.
+
+musb->periodic[] flag setting is also updated.It use to set this flag for
+an endpoint even when only rx or tx is used.Now flag setting is done on
+rx/tx basis of an endpoint.
