Memory associated with a mobile communication device, such as memory removably inserted into a memory card slot, may be accessed, in the alternative, by a mobile communication platform or by a remote USB host. A memory access module connected to the memory card slots is operative in one of two modes: a pass-through mode and a USB mode. In the pass-through mode, the memory card slots are directly connected, via switching circuits, to memory interfaces on the mobile communication platform. A USB interface on the mobile communication platform may additionally be connected, in pass-through mode, via a USB hub to a remote USB host. In the USB mode, the memory card slots are connected, via switching circuits, second memory interfaces, and a controller, to a USB hub supporting USB 3.0 transfer protocols, and accessible by a remote host.
A mobile communication device operative to store and retrieve data to one or more removable memory modules, and having a USB connection for connecting to a remote host via at least first and second revisions of the USB specification, the second revision supporting higher bandwidth data transfer than the first revision, the device comprising:
