Just try to get a new apalis TK1 Module on Evaluation board running.

My USB keyboard works perfect with the “Toradex Easy Installer”. I choose “Linux LXDE Image Version 2.8b5”. After installation and reboot i get the LXDE Desktop but the USB keyboard is not working. My USB mouse works perfect.

lsusb tell me:

Bus 001 Device 006: ID 17ef:608a Lenovo 
Bus 001 Device 007: ID 046a:0023 Cherry GmbH CyMotion Master Linux Keyboard G230
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 0424:2514 Standard Microsystems Corp. USB 2.0 Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

OK he found my cherry keyboard.

I replug both, mouse and keyboard and get the following dmsg output:

I missing the message that the HID driver takes over the keyboard.

I found a keyboard that works. This seems to be a specific problem with the mentioned model.

I ran into a similar problem some months ago. I needed to add “CONFIG_HID_CHERRY=y” to the kernel configuration and recompile it. You can write the current config into a file with: “cat /proc/config.gz | gunzip > running.config” and check wether or not this flag is set. Good luck.
