@Chinpokomon: did you get any solutions to fix this issue? Even i'm hving similar kind of issue. Past 2 days am trying to connect and list my Samsung Captivate Device in Ubuntu, but i failed everytime. Here is my environment
Launching Ubuntu 10.10 (guest OS) from Windows 7 (host OS) using Virtual Box 4.0
In the host OS (Windows 7), i have enabled USB Device Filter for Samsung_Android, and i could see that device in Ubuntu 10.10, but when i use 'lsusb', it doesn't list the samsung device. Any help would be greatly appreciated.
