virtual Device* UsbMassStorageDevice::getDevice ( )

inlinevirtual

Get a usable Device for this particular UsbDevice, if it has a subtree.

Returns: NULL if this operation is not supported.

Reimplemented from UsbDevice.

Definition at line 55 of file UsbMassStorageDevice.h.

void UsbMassStorageDevice::initialiseDriver ( )

virtual

Implemented by the driver class, initialises driver-specific stuff.

Todo:: Some mass storage devices don't support this command, fail to return logical information, or just report incorrect data. All that needs to be handled.

Reimplemented from UsbDevice.
