Hello, Yet another issue with a braille device using the same ID as a serial converter. The Seika driver is the culprit here, stealing 0x10c4:ea60 devices.
This kind of bug is really a concern. Ideally distros should be able to autostart brltty when a USB braille device is plugged in. If braille manufacturers don't take care of using their own IDs, there is no way we can achieve that without hitting people using such serial converters...

The device is part of a Xilinx FPGA board and is a "10c4:ea60 Cygnal Integrated Products, Inc. CP210x Composite Device". Every time I plugged in the device, dmesg showed the device coming up and 'brltty' did *something* to it. At this point, no device was present in '/dev'.
