From d86b8853e1f0c7ffb917a7a48f2e44bc3d8e9f8a Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sun, 26 Feb 2012 16:14:46 +0100 Subject: [PATCH] usb-redir: Limit return values returned by iso packets The usbredir protocol uses a status of usb_redir_stall to indicate that an iso data stream has stopped (ie because the urbs failed on resubmit), but iso packets should never return a result of USB_RET_STALL, since iso endpoints cannot stall. So instead simply always return USB_RET_NAK on iso stream errors.
