Michael D Kinney b4e96b82b4 MdeModulePkg/UsbBusDxe: Add UsbControlTransfer() error check ... https://bugzilla.tianocore.org/show_bug.cgi?id=767 The USB I/O Protocol function ControlTransfer() has a DataLength parameter that specifies the size of the Data buffer. The UsbBusDxe module implements the USB I/O Protocol using the services of the USB2 Host Controller Protocol. The DataLength parameter in the USB2 Host Controller Protocol ControlTransfer() service is an IN OUT parameter so the number of bytes actually transferred is returned. Since the USB I/O Protocol ControlTransfer() service can not return the number of bytes actually transferred, the only option if the number of bytes actually transferred is less than the number of bytes requested is to return EFI_DEVICE_ERROR. The change fixes an issue with a USB mass storage device that responds with 0 bytes to the Get MAX LUN command.
