[ASK] SnowOsx 10.6.X installation issue on lenovo U330

Hi all, I'm new to hackintosh. Nowadays I'm installing Snow Osx 10.6.X on Lenovo notebook series U330 and facing few obstacles.

1. On normal mode, laptop keyboard and touchpad aren't working after first reboot BUT usb portable mouse is working properly. On the contrary, in "safe boot" all devices are working normally. why??, I capture same issue from this thread , but I don't try it yet because the next issue below.

2. this last issue that too ridiculous I think, besides CD-ROM and usb mouse is going normally, but my usb flash disk and portable hard drive aren't being recognized in both mode. Why?, is there any incompatible issue in lenovo?

anyone has the the same problems???, any idea for solving this?

Really thanks in advance. :)
