From b7bdcb79de6de32e40dcc85a5e8c669bec2483d5 Mon Sep 17 00:00:00 2001 From: Dmitry Krivoschekov Date: Sat, 21 Feb 2009 15:30:15 -0800 Subject: [PATCH] USB: musb: fix musb_host_tx() for shared endpoint FIFO The input queue should be used for TX on endpoints which share FIFO hardware. The host TX path wasn't doing that. Shared FIFOs are most often configured for periodic endpoints, which are mostly used for RX/IN transfers ... that's probably how this bug managed to linger for a long time.
