From 4c51b7a0556c0728ed8fb0e293272a9058ece6f5 Mon Sep 17 00:00:00 2001 From: Micah Dowty Date: Fri, 19 May 2006 11:26:24 -0700 Subject: [PATCH] [PATCH] USB: Allow high-bandwidth isochronous packets via usbfs This patch increases an arbitrary limit on the size of individual isochronous packets submitted via usbfs. The limit is still arbitrary, but it's now large enough to support the maximum packet size used by high-bandwidth isochronous transfers.
