Thanks Danfozzy, I loaded: USBHID-Generic-341-PL3DEF-PSNECO and now I can see all the games and the GAMEZ partition again.
This will make me look a little dumb, but I'm really new to this scene (as oposed to wii and iPhone).
Thanks for the patience, I'm sure my problems will help someone else in the future :)
Guys i have very strange thing today. I install first time today multiman. Last version of course. And i browse my game in multi man and he download a covers. Everything nice. But when i leave for a moment room and kid grab a dualshock and press some buttons ! :/ When i go back only 9 of my game was a visible in multiman. (I have about 25games). SCARY !!! Frist i thing kid press delete buton some times and delete my games :( I go exit to XMB and enter to OM 1.17.2 and on his list of game only 9 was a properly tittle and others 16 was visible like BLESxxxx BLUSxxx and can`t launch this:/. I exit OM. shutdown ps3 and restart console. SCARY TIME PART 2 ! I hear a sounds runing ps3 but on screen only BLACK ! What`s going on ! Restart again without jailbreak. And ps3 ask me to set up video and audio output from begining. I set it and i see XMB ufff ! One more time restart with jailbreak and go to OM and MULTIMAN. Every game see properly. UFF !! And my question. What was that ?!?! What kid must press to do this thing ?? Or what was that...
The kid probably hit "R1" button. It enables "usb patch" mode which can affect permissions but nothing permanent. After a restart all is okay (or even without restart). It depends on what payload you're using.
Guys, what do you think of a small application like the BD-ROM one which I posted few days ago...
It will appear on your XMB/GAME column but will allow you to start the LAST game you launched with multiMAN.
1) Start your PS3
2) Launch multiMAN and play a game
3) Turn off the PS3
4) Later turn on the PS3
5) Launch the game you played directly from the XMB without opening multiMAN again
