PID #1 Endpoints: Consumer Usge Page Input and Output (Hid Usage Page 12, Hid Usage 1), Mouse (Hid Usage Page 1, Hid Usage 2), Joystick (Hid Usage Page 1, Hid Usage 4).
PID #2 Endpoints: Consumer Usge Page Output (Hid Usage Page 12, Hid Usage 1), Mouse (Hid Usage Page 1, Hid Usage 2), Keyboard (Hid Usage Page 1, Hid Usage 6) and Multimedia (Hid Usage Page 12 and 1, Hid Usage 1 and 128). The use of this PID is mainly for Hardware Mode. Hardware Mode allows users to store macros to the device itself using the MacroWorks 3.1 programming utility. Once the macros are stored they will work on any computer or OS that supports HID.
PID #3 Endpoints: Consumer Usge Page Output (Hid Usage Page 12, Hid Usage 1), Mouse (Hid Usage Page 1, Hid Usage 2), Joystick (Hid Usage Page 1, Hid Usage 4) and Multimedia (Hid Usage Page 12 and 1, Hid Usage 1 and 128). The use of this PID is mainly for Hardware Mode. Hardware Mode allows users to store macros to the device itself using the MacroWorks 3.1 programming utility. Once the macros are stored they will work on any computer or OS that supports HID.
PID #4 Endpoints: Consumer Usge Page Input and Output (Hid Usage Page 12, Hid Usage 1), Boot Mouse (Hid Usage Page 1, Hid Usage 2), Boot Keyboard (Hid Usage Page 1, Hid Usage 6).

The USB HD15 Wire Interface are Android enabled devices in PIDs #1, #2 or #3. This means the device can be enumerated, read (if input report available), and written to on Android OS that support host USB, generally 3.1 or higher. Android OS is not able to enumerate a device with a boot keyboard and thus if the device is in PID #4 it will appear to the Android OS as only a hardware keyboard/mouse, you will not be able to get a handle to it but it will work as a keyboard/mouse assuming there are hardware macros recorded on the keys.

X-keys USB HD15 Wire Interface Input Report

Figure 1: X-keys USB HD15 Wire Interface male pinout. Pin 9=N/A, pin 10=Ground, pin 15=5 volts, pin 13=digital output, pin 14=digital output, the 10 other pins are all digital inputs. There are 4 additional digital inputs via the 2 3.5 mm stereo jacks located on the side of the unit. Jack #1 is located nearest to the HD15 connector and Jack #2 is located nearest to the indicator LEDs.

Report Length: 37 bytes

1. General Incoming Data

This data is returned when new data is detected such as button presses or unit id change. This report can be manually stimulated by sending a Generate Data output report which is very useful for obtaining the initial state of the device immediately after enumeration. This report is available only in PID #1 and PID #4.

D3: Bit 1=NumLock, bit 2=CapsLock, bit 3=ScrLock, bit 4=On Boot (sets the bit when device is booted up by the usb then sets it back to 0) .
Time: If enabled using Enable Time Stamp output report gives a time in ms starting from when the device was plugged into a port in 4 bytes where byte 36 is the LSB or low byte and byte 33 is the MSB or high byte.
Reboot: This is a number that indicates how many times the device has been rebooted by the USB.

X-keys USB HD15 Wire Interface Output Report

The following types of output reports are shown in the summary below. Please be aware that several of these commands result in writing to the device's eeprom which has a limit to the number of writes allowed before it is "burnt out". The manufacturer's specification is 50,000 eeprom writes. Because of this we recommend the commands designated with e be executed rarely and not within timing loops. Note, the first byte listed in this documentation is 0 and represents the report ID. This is not present on some non-PC operating systems. So when sending an output report on Android for example, eliminate this byte.

12. Multimedia Reflector

Sends 2 byte multimedia messages. Must have the device set to a PID with a multimedia endpoint; PID #2 or PID #3. When in this PID there is no input data report available thus users of this feature will not be able to read any data, only write output reports. If desiring this feature users are instructed to use MacroWorks 3.1 programming utility for programming of the buttons and converting to a multimedia PID. This command must be followed with an "up" command with ULo and UHi =0.

Example: My Computer - 0, 225, 94, 01, 0... and send report using WriteData. Then 0, 225, 0, 0, 0... and send report using WriteData. In this example 0194 is the Usage ID for My Computer.

13. Set Version Number

Send this output report to set the Version of the device. This is not the firmware version given in the descriptor but a 2 byte number available on enumeration. The value is "remembered" so if it is changed, using this report, the device must be rebooted. The device can be rebooted by replugging it or by sending the output report : Reboot Device. The device is also rebooted when changing pids using output report: Change PID.

K3: 4th byte of user determined dongle key, any number 1-254.

16. Check Dongle Key

Checks the key that was entered in Set Dongle Key. This is intented to be done by the developer within their own software to determine if the connected X-keys device is the one they sold to the customer. 4 random bytes along with the actual key are entered into the DongleCheck2() hash function of the Piehid32.dll/PieHid32Net.dll which returns 4 bytes. Then after sending this output report a Check Dongle Key input report will be received containing the same 4 bytes returned from the hash if the key matches.
