[PATCH] usbserial: Regression in USB generic serial driver
Kernel version 2.6.13 introduced a regression in the generic USB serial converter driver (usbserial.o, drivers/usb/serial/generic.c). The bug manifests, as far as I can tell, whenever you attempt to write to the device -- the write will never complete (write() returns 0, or blocks).
