Problems with Snap'n Type Keyboard

Hello,

I just bought a Snap'n Type IR keyboard for a very cheap price and I tried getting it to work. I tried all keymaps and used pikey sample to get the signal code for a driver but the psp doesn't receive any signals and no letters or numbers are shown on the display. As I said I tried it with all keyboard drivers included in pikey 0.5. I use cfw 5.00 m33-6 and run pikey 0.5 perfectly with my Hama keyboard. There are no problems with pikey itself running on my psp. But I wanted to try the Snap'n Type keyboard because it was very cheap and it looks pretty nice, but i still can't find a solution for my problem.

Thanks for your help.
