Kwinz, this patch also seemed to fix my U.S. Robotics 5637 Modem (0baf:0303) which was previously gave the same Input/Output Error when accessing /dev/ttyACM0 with kernels 2.6.31-4 to 2.6.31-11. I recompiled using 2.6.31.11.22 from source with this patch, and it works beautifully. This is appears to be reported upstream at http://bugzilla.kernel.org/show_bug.cgi?id=14103 Hopefully this means it will included for a fix with 2.6.31.1. I hope Karmic will include the fix too.
