My SMK-85 is having some strange malfunctioning. It is connected to the computers usb port via a "spacecraft" converter and from time to time it stops from responding. Restarting the computer have not helped. I have had to turn of the machine and turn it on again, then everything have worked flawlessly.
Now it has happened again but despite several attempts to turn off and turn on the computer the keyboard is still partially dead. The NumL led flickers on upstart and is permanentlly lit when the computer is on.
What could this be? Have the converter broken down or , heaven forbid, is there some problem with the keyborad?
