Hi,
No you can't update it, USB controller devices are managed by Microsoft since Windows 10 & system drivers must be used.
Regarding your DPC latency issue, you can try this TIPS (also visible at the bottom of the first post of all my drivers threads) :
Note : Normally your USB controller devices should already be in MSI mode, but the latency of other devices can impact the latency of your USB controller devices (so if your other devices are compatible with MSI mode and they are not already in MSI mode, switch them to MSI mode (by checking the msi box corresponding to the devices eligible for MSI mode > Apply > Restart your PC).
Thanks MoKiChU
Yes I already have the USB controller in MSI mode.
Apologies for derailing this thread further, but do these MSI settings look ok?
I think everything that can be in MSI mode is, but what about all those PCI Express Root things.
And should some things be switched to High Priority? (Although I have heard that this can be risky)

Yes, it's OK. I don't advise you to change Interrupt Priority (either it is implemented by the driver, or priority management and relegated to the system).
