I'm an owner of a Trust GXT 18 keyboard that doesn’t work with Linux.. I've read around the internet, that if I increase the HID_MAX_USAGES (something to do with usb devices) I could get it to work, so the question is:

How can I increase it?

If you see another solution, please tell me, because I don't want to mess around system commands unless if is the only way to get it working!

Unfortunately there is no way around (at least that I know of) other than installing a newer kernel until Ubuntu uses a 3.6 kernel.

See this page for more information: Linux support for the Trust GXT 18 keyboard

Installing a newer-than-Ubuntu-stable kernel is not that hard and does not require compiling (edited your post). See this answer on how to install precompiled kernels from Also, Ubuntu does backport fixes to the stable kernels. Feel free to open a bug report to get this fix included in the Ubuntu stable kernels. – gertvdijk Jan 30 '13 at 17:04
