So I flashed the zip using clockwork mod recovery (from Rom Manager) and was successful although when I started my phone and connected an USB mouse it didn't light(the mouse) and it wasn't working.
I want to ask here,what's wrong?
I downloaded the app USB host controller and when I opened it it told me that "S3C USB Host driver NOT found!"
I've found this blog (it's in Hungarian so I translated it using Google) talking about exactly my state and it says that I need a Y-Cable to feed the usb peripheral with power, so I'm going to try that and then I'll report here.
