## Can't Program on Linux ## Can't Program on Linux
You will need proper permission to operate a device. For Linux users see udev rules below. Easy way is to use `sudo` command, if you are not familiar with this command check its manual with `man sudo` or this page on line. You will need proper permissions to operate a device. For Linux users, see the instructions regarding `udev` rules, below. If you have issues with `udev`, a work-around is to use the `sudo` command. If you are not familiar with this command, check its manual with `man sudo` or [see this webpage](https://linux.die.net/man/8/sudo).
In short when your controller is ATMega32u4, An example of using `sudo`, when your controller is ATMega32u4:
$ sudo dfu-programmer atmega32u4 erase --force $ sudo dfu-programmer atmega32u4 erase --force
$ sudo dfu-programmer atmega32u4 flash your.hex $ sudo dfu-programmer atmega32u4 flash your.hex
$ sudo dfu-programmer atmega32u4 reset $ sudo dfu-programmer atmega32u4 reset
or just or just:
$ sudo make <keyboard>:<keymap>:dfu $ sudo make <keyboard>:<keymap>:dfu
But to run `make` with root privilege is not good idea. Use former method if possible. Note that running `make` with `sudo` is generally *not* a good idea, and you should use one of the former methods, if possible.
## WINAVR is Obsolete
It is no longer recommended and may cause some problem.
See [TMK Issue #99](https://github.com/tmk/tmk_keyboard/issues/99).
## USB VID and PID
You can use any ID you want with editing `config.h`. Using any presumably unused ID will be no problem in fact except for very low chance of collision with other product.
Most boards in QMK use `0xFEED` as the vendor ID. You should look through other keyboards to make sure you pick a unique Product ID.
Also see this.

You can buy a really unique VID:PID here. I don't think you need this for personal use.

@ -33,7 +33,7 @@ The state of the Keymap layer is determined by two 32 bit parameters:
* **`default_layer_state`** indicates a base keymap layer (0-31) which is always valid and to be referred (the default layer). * **`default_layer_state`** indicates a base keymap layer (0-31) which is always valid and to be referred (the default layer).
* **`layer_state`** has current on/off status of each layer in its bits. * **`layer_state`** has current on/off status of each layer in its bits.
Keymap layer '0' is usually `default_layer`, wither other layers initially off after booting up the firmware, although this can configured differently in `config.h`. It is useful to change `default_layer` when you completely switch a key layout, for example, if you want to switch to Colemak instead of Qwerty.
