Yes, weird it is. The 't' is missing because the keyboard is not able to detect it anymore, because four other keys are being pressed (due to the design of the keyboard, which allows only certain keys being detected at the same time). The keyboard only detects the condition "too many keys pressed", hence the 0x01 packet. > Is this a general behaviour? Do we see the same on other keyboard? I have only the diNovo, and it does this every time. A brief search through the ML archives revealed: http://sourceforge.net/mailarchive/message.php?msg_id=8762071 It seems that at least other Logitech keyboards express similiar behaviour. I believe my patch is the least intrusive fix for handling the odd packet.
