[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.
