Reassigning. The problem is indeed the USB id. USB id 10c4:ea60 is registered in brltty-5.5/Autostart/Udev/rules. 10C4:EA80 has the same problem: # Device: 10C4:EA60 # Generic Identifier # Vendor: Cygnal Integrated Products, Inc. # Product: CP210x UART Bridge / myAVR mySmartUSB light # BrailleMemo [Pocket] # Seika [Braille Display] ENV{PRODUCT}=="10c4/ea60/*", ENV{BRLTTY_BRAILLE_DRIVER}="mm,sk", GOTO="brltty_usb_run" # Device: 10C4:EA80 # Generic Identifier # Vendor: Cygnal Integrated Products, Inc. # Product: CP210x UART Bridge # Seika [Note Taker] ENV{PRODUCT}=="10c4/ea80/*", ENV{BRLTTY_BRAILLE_DRIVER}="sk", GOTO="brltty_usb_run" According to kroesche from Silicon Labs, the correct assignment for these two USB ids are: 10C4:EA60 CP210x UART Bridge https://usb-ids.gowdy.us/read/UD/10c4/ea60 10C4:EA80 CP2110 HID UART Bridge https://usb-ids.gowdy.us/read/UD/10c4/ea80 So this is cleanly a fault of Braille device manufacturer. Vendor ignored rules and released their devices with the unchanged default UART Bridge USB id. They even did not request custom product id from Silicon Labs. https://www.silabs.com/products/interface/request-product-id brltty udev rule either has to add a helper to identify the Braille device (without breaking of other serial devices), or we have to live with a Braille device that does not work out of the box and needs configuration. As CP210x are very common, it is even possible that brltty udev configuration would require to configure exact USB connector. Otherwise the user of Braille device would not be able to use a wide set of devices (GPSes, AVR programmers, serial converters etc.). -- You are receiving this mail because: You are on the CC list for the bug.
