CamiaExact same issue. A workaround that worked until my company changed I.T. & Virus Control this morning was booting windows with driver signatures turned off, install it, then restart normally.
However it boils down to Topping not having a properly signed (or currupted) driver.
I have contacted them about the issue, and I suggest you do so also. I'll report back with what I hear.
Camia (From Topping)
Thank you for contacting TOPPING support. We are happy to assist.
The driver which D30 use is from XMOS's website, since XMOS haven't release newer version, we could not solve this problem yet. Only solution is close the signature verification and try again. Sorry for this matter.
Best Regards!

CamiaIt is normal. Just turn off driver signature. A lot of venderos does not sign their drivers because it cost something. For example Mojo drivers are also unassigned and Mojo cost much more than this Topping.
BTW i use newer version of XMOS driver for D30 under W10. The driver from SMSL M8...
BENSHEEIf these products are so expensive, how could they not afford to get their drivers validated and signed? Surely these companies can afford a few hundred bucks per product line. I think WHQL certification from Microsoft cost like $250 or something.
techwizI feel yuh
Worse is the Micca Origen and Origen +, you have to boot the computer in testing mode to install drivers and run the scripts that come with the driver download.
But it seems like with their latest iteration (Origen G2) they have fixed that problem. I hope Topping (or XMOS) retrofix the drivers for these.
