  @Antonio-Ramos I've built in the necessary kernel modules to support Human Interface Devices (HID) over USB.
  Run oupgrade -force to grab build 216 that has all of the required updates.
  If anyone is interested, the modules added were:

  kmod-hid kmod-usb-hid kmod-input-evdev Some instructions on using a HID with the Omega:

  Once the device is plugged in, dmesg will show something along these lines:

  [ 923.700000] usb 1-1.4: new low-speed USB device number 9 using ehci-platform [ 923.830000] input: BTC USB Multimedia Keyboard as /devices/platform/ehci-platform/usb1/1-1/1-1.4/1-1.4:1.0/0003:046D:C313.0008/input/input4 [ 923.840000] hid-generic 0003:046D:C313.0008: input,hidraw1: USB HID v1.10 Keyboard [BTC USB Multimedia Keyboard] on usb-ehci-platform-1.4/input0 [ 923.920000] input: BTC USB Multimedia Keyboard as /devices/platform/ehci-platform/usb1/1-1/1-1.4/1-1.4:1.1/0003:046D:C313.0009/input/input5 [ 923.930000] hid-generic 0003:046D:C313.0009: input,hiddev0,hidraw2: USB HID v1.10 Device [BTC USB Multimedia Keyboard] on usb-ehci-platform-1.4/input1

  You can then run lsusb to see more info on your device:

  root@Omega-0100:/# lsusb Bus 001 Device 002: ID 0835:8500 Bus 001 Device 001: ID 1d6b:0002 Bus 001 Device 003: ID 0835:8501 Bus 001 Device 009: ID 046d:c313 Bus 001 Device 005: ID 0835:8500 Bus 001 Device 006: ID 0835:8502

  My keyboard was mapped to device 9 (I'm using a powered USB hub), so the Device 009 ID matches the identifier for Logitech keyboards.

  Take a look at /proc/bus/input/devices for more info on the keyboard you've plugged in:

  root@Omega-0100:/# cat /proc/bus/input/devices I: Bus=0003 Vendor=046d Product=c313 Version=0110 N: Name="BTC USB Multimedia Keyboard" P: Phys=usb-ehci-platform-1.4/input0 S: Sysfs=/devices/platform/ehci-platform/usb1/1-1/1-1.4/1-1.4:1.0/0003:046D:C313.0008/input/input4 U: Uniq= H: Handlers=event0 B: PROP=0 B: EV=120013 B: KEY=10000 7 ff9f207a c14057ff febeffdf ffefffff ffffffff fffffffe B: MSC=10 B: LED=7 I: Bus=0003 Vendor=046d Product=c313 Version=0110 N: Name="BTC USB Multimedia Keyboard" P: Phys=usb-ehci-platform-1.4/input1 S: Sysfs=/devices/platform/ehci-platform/usb1/1-1/1-1.4/1-1.4:1.1/0003:046D:C313.0009/input/input5 U: Uniq= H: Handlers=event1 B: PROP=0 B: EV=13 B: KEY=2000000 387a d801d6a1 1e0000 0 0 0 B: MSC=10

  Since this is an input device, it will get mapped to /dev/input:

  root@Omega-0100:/# ls /dev/input/ event0 event1

  To read data from the keyboard, run cat /dev/input/event0 | hexdump
  Each key press generates a lot of data:

  root@Omega-0100:/# cat /dev/input/event0 | hexdump 0000000 5642 5f73 0000 b58c 0004 0004 0007 0012 0000010 5642 5f73 0000 b58c 0001 0018 0000 0001 0000020 5642 5f73 0000 b58c 0000 0000 0000 0000 0000030 5642 5f73 0001 ee07 0004 0004 0007 0012 0000040 5642 5f73 0001 ee07 0001 0018 0000 0000 0000050 5642 5f73 0001 ee07 0000 0000 0000 0000 0000060 5642 5f76 000b 3627 0004 0004 0007 0010 0000070 5642 5f76 000b 3627 0001 0032 0000 0001 0000080 5642 5f76 000b 3627 0000 0000 0000 0000 0000090 5642 5f76 000c 4f6d 0004 0004 0007 0010 00000a0 5642 5f76 000c 4f6d 0001 0032 0000 0000 00000b0 5642 5f76 000c 4f6d 0000 0000 0000 0000

  You'll have to look up how to decode this data. Let us know when you figure it out!
  I don't have a barcode scanner to test, but I imagine that it will work the same way.

  Happy hacking!

  Just to update this thread. Have just used a breadboard PSU with 3.3v on the Vin pin and hooked up the ground.

  All worked perfectly, unfortunately onion doesnt fit my breadboard as its too small!

  Just for good measure I hooked up an LED (with resistor in series) to the GPIO. I used the console, gpioctl and fast-gpio to turn it on and off and can report all worked :D

  @niels-teekens Really sorry about the GUI issue. Apparently, we used a javascript keyword that's not available in Firefox (let as opposed to var). Glad you have it sorted out. :)

  I have the same issue and I'm currently making a new topic for it (Lazar asked me to do this after I first posted to the ticketing system).

  A friend and I managed to hack into the omega by interupting the boot sequence an replacing init with sh. Then we were able to see the crypted password, wich in turn googled to the string '5up'. This seems to be the OpenWRT standard root password.

  So try to log in with: root & 5up

  @Theodore-Borromeo You won't need to email us manually to be assigned a secret token. Once we've released the cloud integration, you will be able to log into a page on our website where you can manage and generate new secret tokens.

  Hope this answers your question :)

  @Shamsul-Tehahmad The Omega has only 1 set of UART port and it is reserved for the Linux terminal. Your best option right now is to use a 3.3V USB to Serial adapter an plug it in to the USB port on the Expansion or Mini Dock.

  Best,
  Zheng

  @Sawyer-McBride Yup, it will be released fortnightly. We are actually constantly making changes to the Console. We just want to first get into the habit of releasing Console updates regularly, and then we can adjust the frequency of the updates to suit the community :)

  Hi @Brian-Moreau, the Omega itself does not have an on-board ADC, so if you want to use it to read analog sensor data, you will need the Arduino Dock. It does have PWM output, and as @Kit Bishop pointed out, you can use fast-gpio to control the PWM output. More information about the fast-gpio library/command can be found here: https://onion.freshdesk.com/support/solutions/articles/6000069970-can-i-do-pwm-with-the-expansion-dock-.

  Good job! I'm planning on using my relay expansion for a Remote Power Strip test :) this will be useful!!

  edit:
  Of course I need my battery expansion first! But it'll get here when it gets here, can't wait!

  Hello everybody,

  I've decided to make a new reply.
  Minutes ago I've tested to connect my Omega and my T520 without limitations to the 802.11b/g/n. What shall I say? It just works fine for both devices, so there seems to be some problem with my router at home.
  Therefor I'd say that this problem is solved.
  Thanks to everybody who helped me!

  you shouldn't use Firefox - it doesn't handle the response properly. I had to use Chrome or Microsoft Edge
  I was just add that Opera too seems to work ok.

  Support for Firefox and Safari will be added starting from next console release. Stay tuned :smile:

  Yeah.. seems to be sensible if you are going to pin to 15.05 better to use their kernel source and patch it only if needed for drivers and firmware. Thanks.

  In connection to this, I am using my Omega with an Arduino shield (primarily because I have quite a bit invested in Arduino shields).
  Among the shields I have is the Adafruit PowerBost 500 shield (https://www.adafruit.com/products/2078) with a 2000mAh lithium ion battery.
  When plugged in to the Omega Arduino shield, this powers the Omega fine.

  Speaking of I2C, we're releasing documentation for a C-based I2C library for the Omega sometime next week.
  Stay tuned!
