I'm reinstalling Windows 10 from scratch on an HP Z820 and I've been unable to find the driver for the device identified as PCI Serial Port in Device Manager. I tried running and manually installing sp74499.exe from Paul_Tikkanen's post in this thread, but when I did, it said it could not find the device for this driver.
The Hardware IDs listed for the device are
PCI\VEN_8086&DEV_1D3D&SUBSYS_158B103C&REV_05
PCI\VEN_8086&DEV_1D3D&SUBSYS_158B103C
PCI\VEN_8086&DEV_1D3D&CC_070002
PCI\VEN_8086&DEV_1D3D&CC_0700
Anyone know where to get the correct driver?
