Endpoints can stall when an error occurs. The USB Mass Storage Bulk-Only Transport specification lists some situation in which a bulk endpoint can stall. For example, when a device has less data to send than the host expects, it sends a stall. Some controller drivers are unable to stall bulk endpoints correctly. The can_stall parameter tells the driver whether it should use stalls. Alan Stern ------------------------------------------------------- This SF.Net email is sponsored by the JBoss Inc.
