I've prepared a fresh Centos 6.3 x64 virtual machine on Virtualbox with android development environment, also installed the guest additions with the Extension Pack for Virtualbox.
When I connect my android device via usb, Virtualbox does find it and I can attach it easily with no problems by selecting devices usb devices SAMSUNG_Android, then Virtualbox shows the device as connected but the android device does not show the usb connection notification any more : USB connected Select to copy files to/from your computer.
On cent terminal I try adb devices command and it doesn't find anything.
When I try lsusb on terminal before and after attaching the device, it returns the same result.
Please help me find where is the problem.
