I'm on Windows 10 with an up to date computer and am having trouble with dpc latency and this driver (spikes of cpu usage).  I've exhausted my research on the net, done just about everything.  I thought I'd ask here.  Has any one found any way to deal with this? A Lot of reported problems on the net, only real solution seems to be a clean install of windows 10! It spikes with nothing attached to any of the usb ports btw, others have reported the same problem.

You could try a project instead of trusting these latency checkers. 90% of the solutions seems to be at least 5 years old and are not easily fixable.
