The Rocktech BM102 is a USB-based, 2-channel oscilloscope with an analog bandwidth of 20MS/s and 50MS/s sampling rate.
This device appears to be a rebadge of the SainSmart DDS120 (or vice versa). The lsusb is exactly the same, the PCB is exactly the same (both have a "656517" and "102LJT1402" silkscreen), and the components used appear to be the same as well.
See Rocktech BM102/Info for more details (such as lsusb -v output) about the device.
