From d61000a8b1d99c5155440b727ea32f12a4988120 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Fri, 2 Mar 2012 21:27:20 +0100 Subject: usb: add USB_RET_IOERROR We already have USB_RET_NAK, but that means that a device does not want to send/receive right now. But with host / network redirection we can actually have a transaction fail due to some io error, rather then ie the device just not having any data atm. This patch adds a new error code named USB_RET_IOERROR for this, and uses it were appropriate. Notes: -Currently all usb-controllers handle this the same as NODEV, but that may change in the future, OHCI could indicate a CRC error instead for example. -This patch does not touch hw/usb-musb.c, that is because the code in there handles STALL and NAK specially and has a if status < 0 generic catch all for all other errors Signed-off-by: Hans de Goede Signed-off-by: Gerd Hoffmann --- usb-linux.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'usb-linux.c') diff --git a/usb-linux.c b/usb-linux.c index 38df9e613e..050ea7a87d 100644 --- a/usb-linux.c +++ b/usb-linux.c @@ -369,7 +369,7 @@ static void async_complete(void *opaque) break; default: - p->result = USB_RET_NAK; + p->result = USB_RET_IOERROR; break; } @@ -729,7 +729,7 @@ static int urb_status_to_usb_ret(int status) case -EOVERFLOW: return USB_RET_BABBLE; default: - return USB_RET_NAK; + return USB_RET_IOERROR; } } -- cgit v1.2.3-55-g7522
