The musb driver can drop rx packets when heavily loaded. These two patches address two issues that can cause this. Both issues arose when an endpoint was reprogrammed. The first patch is a logic bug that resulted in a shared_fifo in rx mode not having its state cleared out. The second patch fixes a race condition caused by not stopping the dedicated endpoint for bulk packets before rotating its queue which allowed a packet to be recieved and then thrown away. V2 added a comment and removed debugging code Andrew Goodbody (2): usb: musb: Ensure rx reinit occurs for shared_fifo endpoints usb: musb: Stop bulk endpoint while queue is rotated drivers/usb/musb/musb_host.c | 19 ++++++++++++------- 1 file changed, 12 insertions(+), 7 deletions(-) -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
