The YiXingDianZi MDSO (also known as Wosontel MDSO) is a USB-based, 2-channel oscilloscope with an analog bandwidth of 20MS/s and 48MS/s sampling rate.

It comes in very compact plastic case (82x65x23mm) without any branding, USB type B input, 2c BNC inputs, and a red LED.

The YiXingDianZi manufacturer is probably the same as Instrustar (Chinese characters match, lsusb is almost exactly the same).

See YiXingDianZi MDSO/Info for more details (such as lsusb -v output) on the device.
