Hi
Both USB-MSD device and USB-MSD host loaders are available in the uTasker serial loader project. TWR-K60D100M versions are at:
http://www.utasker.com/kinetis/TWR-K60D100M.html
This is not two different projects but a single one where the host or device mode is configured by a single project define.
The USB mode can also be combined with UART, SD card, Kboot compatible UART/USB-HID or Ethernet loaders simply be enabling or disabling the appropriate defines.
It works on all K, KL and KV boards with USB host support so doesn't require porting between devices. The project also builds with most IDEs (CW, KDS, IAR, Keil, Crossworks, CooCox, Atollic, Green Hills etc.) so again is not restricted to a certain environment.
The USB-MSD host is a recent addition to the project's capabilities and an automatic device/host mode is foreseen shortly, whereby the loading works either by connecting the board to a PC host (device mode) or by plugging in a memory stick (host mode) and the corresponding operation is detected and configured accordingly (on-the-fly). Potentially also cloning software between two boards by connecting them together (OTG).
The operation can also be simulated in VisualStudio using the uTasker Kinetis simulator, which allows fastest developments coupled with exceptional software auditing and maintenance capabilities.
Below is an example of the the USB-MSD output during operation (on TWR-SER RS232 interface) with a typical memory stick.
