Installing USB drivers with DPInst.exe not working

[Floyd]

Hello to all,
Here is my problem i'm using DPInst.exe 2.1 and i tried to install ftdibus.inf and ftdport.inf USB drivers . I was using legacyMode because this are unsigned USB drivers. & I did the successful installation with Dpinst.exe but still i gets promt with the message "Find New hardware" when plugs in my USB devices. Please help me out. And tell me the reason why this is happening.

I'm facing exactly same thing . If some buddy have solution then please lead us. Apparently a windows hotfix is responsible for this and unfortunately it has no uninstall functionality. I will get back to you if I manage to pinpoint the hotfix that is the culprit.

If the hardware is usb connected then that would make it a PNP device. Have a look at the links at PNP Device Driver. You can use INF2CAT to create a .CAT file and you will have to sign this with either a existing certificate or create one.
Inf2Cat.exe /driver:"<Path to driver files>" /os:XP_X86 /verbose
Step-by-Step Guide to Device Driver Signing and Staging
Authenticode will work on Windows XP even it Microsoft not state this.

This should solve the issue with the hardware wizard.
