Sorry about the lack of communication on this. Yes, you have our new SDRx, which integrates the USB hub, amplifier, and RTL-SDR on one board. The black data cable connects the SDRx to the CHIP. And then power needs to be provided to the CHIP's microUSB.
Yes, the two USB ports allow for external storage to be added. I guess it's possible they could also be used for another RTL-dongle...diversity reception.
@Tysonpower Yes, we're phasing out the old kit and replacing the separate dongle and LNA with SDRx. From the orders in the last month, about half will receive the old-style kit. And the other half will receive SDRx.
