I have this cheapie 44x11 programmable LED badge that I am trying to access under Linux. I *think* its the same as this device ... https://github.com/Caerbannog/led-mini-board ... but when I connect it to a USB port no /dev/ttyU* or /dev/ttyA* is created. Output of dmesg ... usb 2-5: new full-speed USB device number 21 using xhci_hcd usb 2-5: New USB device found, idVendor=0416, idProduct=5020 usb 2-5: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 2-5: Product: LS32 Custm HID usb 2-5: Manufacturer: LSicroelectronics hidraw: raw HID events driver (C) Jiri Kosina usbcore: registered new interface driver usbhid usbhid: USB HID core driver input: LSicroelectronics LS32 Custm HID as /devices/pci0000:00/0000:00: 14.0/usb2/2-5/2-5:1.0/0003:0416:5020.0001/input/input14 hid-generic 0003:0416:5020.0001: input,hidraw0: USB HID v1.10 Device [LSicroelectronics LS32 Custm HID] on usb-0000:00:14.0-5/input0 ... and of lsusb ...

I did come across this one comment in a discussion thread for a different device ... https://www.reddit.com/user/k2539/ ... with no response. Any advice about how go forward would be appreciated! Thanks. -- (o< .: Per curiositas ad astra .: http://www.circuidipity.com (/)_
