Host is Ubuntu Linux 8.04. The device is an HTC Mogul (PPC-6800). The device appears as ""HTC Generic RNDIS"". The actual ""symptoms"" inside the Guest vary... sometimes the device shows up in Hardware Manager (as ""Windows-mobile network adapter""). Other times it doesn't show up at all, and other times it shows up with a red icon next to it indicating a problem status. In no cases will ActiveSync ever recognize that you have a mobile device plugged in. All other USB devices that I've tried work fine inside the Guest. MY WORKAROUND: To make it work I have to make one setting change on the PDA itself. Go to Settings -> Connections -> USB to PC. UNCHECK the box that says ""Enable advanced network functionality"". My device sometimes hangs trying to apply this setting.. if so use the soft reset hardware button, then try again. This setting totally changes how the device behaves on the USB bus.. it now appears as ""HTC Generic Serial"" and with different USB IDs, etc, and it uses different protocols to communicate with the Host Adapter (it's a lot of black magic I don't know too much about). This issues really does need to be resolved somehow, as I actually want to be able to use the ""advanced network functionality"" that my PDA has to offer. I'm happy to assist in debugging and development, including remote access to systems where you can access my device if that would be of any assistance. I've attached the output of two commands to this ticket. ""VBoxManage list usbhost"" and ""lsusb"".",defect,closed,USB,VirtualBox 1.6.4,obsolete,,,Windows,Linux
