I'm working on it right now. I noticed what is affecting him. It is the 60 milliseconds timeout that we have to avoid jitter. Since the ilume keyboard has some inertia it thinks that the user is actually pressing the key and that key will take more time to return to its normal position. I tested with 2.6.24 and with 2.6.28 and i see an improvement in accuracy in 2.6.28, and 2.6.24 is no better than 2.6.28 in terms of timings. I tried a smaller interval (about 15 milliseconds) for the jitter problem and things work better. I'll do more tests and send a patch. I would like to do what you suggested earlier (faster conversion rate for initial events), I am doing tests now. N.-
