Hello,

Do you know if it 's possible to support onlykey in Linux container ( Crostini ) ? if yes , I will appreciate instructions to do it.

I’m sure you could. The main thing would be that the host is able to pass-through the USB device to the container. If the device shows up with lsusb and the UDEV rule is applied then the OnlyKey CLI should work fine [Using OnlyKey with Linux | Docs](https://docs.onlykey.io/linux.html)

I don’t currently have a chromebook with crostini to test. I found this, there would need to be a way to share/attach USB device.

It may be that only USB mass storage devices are supported in Crostini, OnlyKey shows up as a USB HID device (A keyboard)
