in fact, your usb hub adds another controller.

unless they are seen by the Windows OS as removeable and "optimized for Better Performance"... then it buffers the transfer. in buffering, the OS may use the cache.

if you want to avoid the caching, you can choose to "optimize for quick removal", instead, which will write directly to the device without caching - but generally will actually slow down the transfer.
