i have ubuntu precise as my host OS.Recently got virtual box version 4.2 PUEL version from the oracle site.installed it and activated the usb 2.0 recognition and installed windows xp in v.box.my primary reason to do this is because i have a customised modem that i can only temporarily unlock in windows then once unlocked i restart and use it in ubuntu after dual booting so was wanting to make my work simpler by having the program in windows xp in v.box.the drivers installed well but i cant connect to the internet via mobile partner plus i installed the "huawei modem unlocker v.5.8.1 by bojs" after installing .NET framework version 2.0 since it needed it but the program cant read the device info.any solution/suggestion/work around?
