USB oscilloscope under linux

Question

linux

Please help me choose a USB oscilloscope. The requirements are as follows:
— at least 2 channels;
- bandwidth 20 MHz (or better 40);
— the possibility of external synchronization;
- galvanic isolation is highly desirable;
- the most important thing: the ability to work under linux! Not necessarily with native software.

Does such a thing exist in nature? So far I have found only Hantek devices (with the OpenHantek library ), but I am not satisfied with the lack of galvanic isolation and the frankly Chinese quality of installation (somewhere there was a photo of the insides).
