i am currently using suse linux 10.2 on my Acer Laptop, and i have installed virtual box on it. i have installed a Vista Os through Virtual box in suse linux.

The problem is that, when i insert a usb device into my laptop, its get detected in my linux. But the problem is when i start my Vista os , i doesn't get detected in Vista. i also have enabled the usb drive option in virtual box settings, but its not getting detected.
Why it so, do i need to do any other configuration.

plz suggest me some solution ...

Thanks in Advance.
