+Subject: [PATCH 14/16] musb: disable PING on status phase of control transfer
+
+PING token is not mandatory in status phase of control transfer
+so some high speed USB sticks doesn't support this.If such devices
+are connected to MUSB then they would not respond to PING token
+causing delayed or failed enumeration.
+
+Fixing this issue by disabling PING token in status phase of control
+transfers.
