From b2d1fe67d09d2b6c7da647fbcea6ca0148c206d3 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 19 Dec 2012 15:08:33 +0100 Subject: usbredir: Add support for buffered bulk input (v2) Buffered bulk mode is intended for bulk *input* endpoints, where the data is of a streaming nature (not part of a command-response protocol). These endpoints' input buffer may overflow if data is not read quickly enough. So in buffered bulk mode the usb-host takes care of the submitting and re-submitting of bulk transfers. Buffered bulk mode is necessary for reliable operation with the bulk in endpoints of usb to serial convertors. Unfortunatelty buffered bulk input mode will only work with certain devices, therefor this patch also adds a usb-id table to enable it for devices which need it, while leaving the bulk ep handling for other devices unmodified. Note that the bumping of the required usbredir from 0.5.3 to 0.6 does not mean that we will now need a newer usbredir release then qemu-1.3, .pc files reporting 0.5.3 have only ever existed in usbredir builds directly from git, so qemu-1.3 needs the 0.6 release too.
