Multiple Litra Devices

[drewksparks]

Hi! I have multiple Litra Beams, and I changed some lines to accommodate this, since it just controls one at a time.
There may be a more elegant/universal solution than this, since it requires pulling the exact device ID.

Step 1 - change litrabase line 17-19 to the below to have the device selected by the DevSrvsID

function hidapi() {
  "./hidapitester" --open-path $1 --length 20 --send-output $2
}

Step 2 - Pull device ID using hidapitester --list-detail in terminal and then copying the DevSrvsID for each Litra device you want to control.

Step 3 - In the litrabeam file (or litraglow, depending on device you have) change to the below, and update lines 10 and 11 to reflect the left/right devices:

#!/usr/bin/env bash

#
# Logitech Litra Beam
#   Vendor ID:	0x046D
#   Product ID:	0xC901
#

# change the below using the values you got from 'hidapitester --list-detail'

#

const_litrabeam_min=0x11,0xFF,0x04,0x4c,0x00,0x1E
const_litrabeam_mid=0x11,0xFF,0x04,0x4C,0x00,0x32
const_litrabeam_max=0x11,0xFF,0x04,0x4C,0x00,0x64
