Conflicting drivers

There’s another company that is doing a competing device driver. It has named it very similarly and has given its files *.sys, *.inf, *.cat - exactly the same names as I did.
We do not share the same Manufacturer ID.
One of my users found out that you cannot install both drivers on the same machine. If you install one then the other installation fails.
Setupapi.dev.log reports: Device has problem: 0x26: CM_PROB_DRIVER_FAILED_PRIOR_UNLOAD.
Is it possible that file name conflict cause this problem?

Could be. One of you has to change
