3 This page details various common questions people have about troubleshooting their keyboards.
7 ## hid_listen can't recognize device
8 When debug console of your device is not ready you will see like this:
11 Waiting for device:.........
14 once the device is pluged in then *hid_listen* finds it you will get this message:
17 Waiting for new device:.........................
21 If you can't get this 'Listening:' message try building with `CONSOLE_ENABLE=yes` in [Makefile]
23 You may need privilege to access the device on OS like Linux.
24 - try `sudo hid_listen`
26 ## Can't get message on console
28 - *hid_listen* finds your device. See above.
29 - Enable debug with pressing **Magic**+d. See [Magic Commands](https://github.com/tmk/tmk_keyboard#magic-commands).
30 - set `debug_enable=true` usually in `matrix_init()` in **matrix.c**.
31 - try using 'print' function instead of debug print. See **common/print.h**.
32 - disconnect other devices with console function. See [Issue #97](https://github.com/tmk/tmk_keyboard/issues/97).
34 ## Linux or UNIX like system requires Super User privilege
35 Just use 'sudo' to execute *hid_listen* with privilege.
40 Or add an *udev rule* for TMK devices with placing a file in rules directory. The directory may vary on each system.
42 File: /etc/udev/rules.d/52-tmk-keyboard.rules(in case of Ubuntu)
44 # tmk keyboard products https://github.com/tmk/tmk_keyboard
45 SUBSYSTEMS=="usb", ATTRS{idVendor}=="feed", MODE:="0666"
52 First you have to compile frimware with this build option `NKRO_ENABLE` in **Makefile**.
54 Try `Magic` **N** command(`LShift+RShift+N` by default) when **NKRO** still doesn't work. You can use this command to toggle between **NKRO** and **6KRO** mode temporarily. In some situations **NKRO** doesn't work you need to switch to **6KRO** mode, in particular when you are in BIOS.
56 If your firmeare built with `BOOTMAGIC_ENABLE` you need to turn its switch on by `BootMagic` **N** command(`Space+N` by default). This setting is stored in EEPROM and keeped over power cycles.

61 ## TrackPoint needs reset circuit(PS/2 mouse support)
62 Without reset circuit you will have inconsistent reuslt due to improper initialize of the hardware. See circuit schematic of TPM754.

68 ## Can't read column of matrix beyond 16
69 Use `1UL<<16` instead of `1<<16` in `read_cols()` in [matrix.h] when your columns goes beyond 16.
71 In C `1` means one of [int] type which is [16bit] in case of AVR so you can't shift left more than 15. You will get unexpected zero when you say `1<<16`. You have to use [unsigned long] type with `1UL`.

76 ## Bootloader jump doesn't work
77 Properly configure bootloader size in **Makefile**. With wrong section size bootloader won't probably start with **Magic command** and **Boot Magic**.
79 # Size of Bootloaders in bytes:
80 # Atmel DFU loader(ATmega32U4) 4096
81 # Atmel DFU loader(AT90USB128) 8192
82 # LUFA bootloader(ATmega32U4) 4096
83 # Arduino Caterina(ATmega32U4) 4096
84 # USBaspLoader(ATmega***) 2048
85 # Teensy halfKay(ATmega32U4) 512
86 # Teensy++ halfKay(AT90USB128) 2048
87 OPT_DEFS += -DBOOTLOADER_SIZE=4096
89 AVR Boot section size are defined by setting **BOOTSZ** fuse in fact. Consult with your MCU datasheet.
90 Note that **Word**(2 bytes) size and address are used in datasheet while TMK uses **Byte**.
92 AVR Boot section is located at end of Flash memory like the followings.
94 byte Atmel/LUFA(ATMega32u4) byte Atmel(AT90SUB1286)
95 0x0000 +---------------+ 0x00000 +---------------+
98 | Application | | Application |
101 | | 32KB-4KB | | 128KB-8KB
102 0x6000 +---------------+ 0x1E000 +---------------+
103 | Bootloader | 4KB | Bootloader | 8KB
104 0x7FFF +---------------+ 0x1FFFF +---------------+
107 byte Teensy(ATMega32u4) byte Teensy++(AT90SUB1286)
108 0x0000 +---------------+ 0x00000 +---------------+
111 | Application | | Application |
114 | | 32KB-512B | | 128KB-2KB
115 0x7E00 +---------------+ 0x1FC00 +---------------+
116 | Bootloader | 512B | Bootloader | 2KB
117 0x7FFF +---------------+ 0x1FFFF +---------------+
120 And see this discussion for further reference.

124 ## Special Extra key doesn't work(System, Audio control keys)
125 You need to define `EXTRAKEY_ENABLE` in `rules.mk` to use them in QMK.
128 EXTRAKEY_ENABLE = yes # Audio control and System control
131 ## Wakeup from sleep doesn't work
133 In Windows check `Allow this device to wake the computer` setting in Power **Management property** tab of **Device Manager**. Also check BIOS setting.
135 Pressing any key during sleep should wake host.
139 **Note that Arduino pin naming is different from actual chip.** For example, Arduino pin `D0` is not `PD0`. Check circuit with its schematics yourself.
141 - http://arduino.cc/en/uploads/Main/arduino-leonardo-schematic_3b.pdf
142 - http://arduino.cc/en/uploads/Main/arduino-micro-schematic.pdf
144 Arduino leonardo and micro have **ATMega32U4** and can be used for TMK, though Arduino bootloader may be a problem.
147 ## Using PF4-7 pins of USB AVR?
148 You need to set JTD bit of MCUCR yourself to use PF4-7 as GPIO. Those pins are configured to serve JTAG function by default. MCUs like ATMega*U* or AT90USB* are affeteced with this.
150 If you are using Teensy this isn't needed. Teensy is shipped with JTAGEN fuse bit unprogrammed to disable the function.
154 // JTAG disable for PORT F. write JTD bit twice within four cycles.
158 https://github.com/tmk/tmk_keyboard/blob/master/keyboard/hbkb/matrix.c#L67
160 And read **26.5.1 MCU Control Register – MCUCR** of ATMega32U4 datasheet.
163 ## Adding LED indicators of Lock keys
164 You need your own LED indicators for CapsLock, ScrollLock and NumLock? See this post.
166 http://deskthority.net/workshop-f7/tmk-keyboard-firmware-collection-t4478-120.html#p191560
168 ## Program Arduino Micro/Leonardo
169 Push reset button and then run command like this within 8 seconds.
172 avrdude -patmega32u4 -cavr109 -b57600 -Uflash:w:adb_usb.hex -P/dev/ttyACM0
175 Device name will vary depending on your system.

181 ## USB 3 compatibility
182 I heard some people have a problem with USB 3 port, try USB 2 port.
186 ### OS X 10.11 and Hub

190 ## Problem on BIOS(UEFI)/Resume(Sleep&Wake)/Power cycles
191 Some people reported their keyboard stops working on BIOS and/or after resume(power cycles).
193 As of now root of its cause is not clear but some build options seem to be related. In Makefile try to disable those options like `CONSOLE_ENABLE`, `NKRO_ENABLE`, `SLEEP_LED_ENABLE` and/or others.
