Commit e0d795e4f36c ("usb: irda: cleanup on ir-usb module") added a USB IrDA header with common defines, but mistakingly switched to using the class-descriptor baud-rate bitmask values for the outbound header.
This broke link-speed handling for rates above 9600 baud, but a device would also be able to operate at the default 9600 baud until a link-speed request was issued (e.g. using the TCGETS ioctl).
People still use this driver/hardware? And this wasn't found until now? wow...
