need help for making this driver work on win7

[ukanoldai]

Hello,
i've some specific hardware i have to make works on windows 7 as we have to reinstall it completely on more than 50 devices.
The driver is for a builtin chip for wich i have no info since the vendor does not exists anymore, but i have to make it works or the device reboot every 5 mins if it is not installed (watchdog style).

the driver does not load on windows 7 but i think it's an .inf issue, message from hdwwiz is that the "data is invalid" but without more information. The device is not pnp since i have to add it manually even on Xp.

here's the inf, i need clues to know where to look, i read some about chkinf, wdbg but i'm a bit lost

I ran your INF file through the chkinf tool for you. Output attached. There were 4 errors, 10 warnings.

Here's one of your BIG problems: The result highlights the fact there's no .cat (Catalog) file for your driver. That tells me this is an unsigned driver. (Among other things, a driver's digital signature is stored in a .cat file)

XP allowed unsigned drivers. That's gonna be a problem with Windows 7. If you Google, i've seen people who've suggested methods how to sign a driver yourself... but I've never tried it nor know if those method actually worked in the past (or still work at this point in time).
