Your hard drives yes, I say 'partition' as that is what you see in Windows Explorer.I asked, because there's only 1 dump present whilst your eventlog shows multiple crashes.

Due to the nature of the crash, I can't say with certainty if what I think is correct, but it looks like there are issues with the Focusrite USB device or its software.
The common meaning of this crash is that there is 1 resource (as a somewhat better description for IRP) that 2 drivers both believe they own. 1 of them succeeds in using the resource and the other fails. In such situations the second driver covers the tracks of the first driver making it difficult to find the first one. Although there's only a minidump, which means the dump can't be analyzed in a matter a complete kernel dump can, it's very likely to be the Focusrite device or software as there are lots of USB related calls.
