From 67c752b41a4238c1a2d7eebcd061ff8c1127d3e9 Mon Sep 17 00:00:00 2001 From: Duncan Sands Date: Fri, 28 Apr 2006 18:44:06 +0200 Subject: [PATCH] [PATCH] USBATM: change the default speedtouch iso altsetting The maximum possible bandwidth for a speedtouch modem is about 7Mbaud. You can only get this by using isochronous urbs (enable_isoc=1) and altsetting 3. With the current default altsetting of 2, the modem maxes out at about 4Mbaud. So change the default altsetting to 3 when using isochronous urbs. It would be nice to base the altsetting on the detected line speed, but that's hard given the current design.
