I notice from your photos that you are relying on USB power only so far. You have no direct PSU plugged into the Arduino.

So a word of warning as you get into adding stuff to your projects that, before going off on any tangents to investigate why the Arduino crashed, you couldn't upload a sketch because communication was lost, etc, ALWAYS use an independent PSU and see if your problem goes away. It will save you a lot of time investigating "possible faulty Arduino's". Just don't fall for it.

NAME
usbconfig -- configure the USB subsystem SYNOPSIS
usbconfig [-u unit] [-a addr] [cmds...] usbconfig [-d [ugen]<unit>.<addr>] [cmds...] DESCRIPTION
The usbconfig utility is used to configure and dump information about the USB subsystem. The options are as follows: -u unit Limit device range to USB devices connected to the given USBUS unit. -a addr Limit device range to the given USB device index. Should only be used in conjunction with the unit argument. -d [ugen]<unit>.<addr> Limit device range to USB devices connected to the given unit and address. The unit and address coordinates may be prefixed by the lowercased word "ugen". -h Show help and available commands. When called without options, usbconfig prints a list of all available USB devices. EXAMPLES
Show information about the device on USB bus 1 at address 2: usbconfig -u 1 -a 2 dump_info Dump HID descriptor for device on USB bus 1 at address 2: usbconfig -u 1 -a 2 do_request 0x81 0x06 0x2200 0 0x100 Dump string descriptor at index Z for device on USB bus 1 at address 2: usbconfig -u 1 -a 2 dump_string Z Dump current configuration descriptor for device on USB bus 1 at address 2: usbconfig -u 1 -a 2 dump_curr_config_desc Dump device descriptor for device on USB bus 1 at address 2: usbconfig -u 1 -a 2 dump_device_desc Program the device on USB bus 1 at address 2 to suspend, resume, power off, go into power save, or power on: usbconfig -u 1 -a 2 suspend usbconfig -u 1 -a 2 resume usbconfig -u 1 -a 2 power_off usbconfig -u 1 -a 2 power_save usbconfig -u 1 -a 2 power_on Display a list of available quirk names: usbconfig dump_quirk_names See usb_quirk(4) for more information on quirks.
