# Linux USB keyboard
|
|
* Got a USB keyboard working with an ramdisk root filesystem.
|
|
* By booting the [Asahi dart/dev kernel](https://github.com/AsahiLinux/linux/tree/dart/dev) with USB3 XHCD, DWC3 and DART et cetera
|
|
* Can use this [Linux config file for M1 MacBook Air with USB](https://github.com/amworsley/asahi-wiki/blob/main/images/config-jannau-iso9660-noR.gz) as a base (doesn't enable gadget mode)
|
|
* Modifying the initrd to just run /bin/sh (edit /init)
|
|
* Booted it directly via ```python3.9 proxyclient/tools/linux.py -b 'earlycon console=tty0 console=tty0 debug' Image-dwc3.gz t8103-j274.dtb initrd-be2.gz```
|
|
* Where the Image-dwc3.gz is the Asahi dart/dev kernel, the t8103.j274.dtb built with that kernel, at **linux/arch/arm64/boot/dts/apple/t8103-j274.dtb**, and initrd-be2.gz is the modified debian Bullseye initrd to just run **/bin/sh** after the set up.
|
|
* Then I used a Type-C to Type-A adapter to plug in a normal old USB Dell keyboard and enter commands into the /bin/sh running.

|
* You can go one step further and try [booting a USB drive](SW-Linux-USB-drive.md)
