[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.
