This patch (as950) fixes a bug in the cdc-acm driver. It doesn't keep track of which interface (control or data) the sysfs attributes get registered for, and as a result, during disconnect it will sometimes attempt to remove the attributes from the wrong interface. The left-over attributes can cause a crash later on, particularly if the driver module has been unloaded.
