Modified Files: src/sys/dev/usb: ucom.c Log Message: ucom(4): Nix broken error branch. This error branch was introduced to make the system act, when a USB serial adapter is yanked, as if the other end had spat out a line feed in an attempt to wake any sleeping readers so they will stop using the USB serial port. This is no longer necessary, because ttycancel will wake them anyway, and it is actually harmful because it puts stuff in the output queue (CR LF) that will never be processed, causing subsequent users to hang trying to open the device. Problem found and patch tested by tih@.
