Code10 after installing own driver on x64 win 7 prof

Robert Suess

Hello everyone,

I tried to install an driver via INF-file for USB-CDC (based on mcb2300_vcom.inf) on Windows 7 Professional x64 (in the following text called 'target system'). This is to get a COM-Port to send data via USB to an LPC2368 microcontroller.

The installation failed the first time with the message that the driver is not a x64-based system driver.

So I changed the driver as described in MSDN-article for "Cross-Platform INF Files". After a day of hard mind-work I finished the driver and tried to install it again. Now the installation starts on the target system, gives a message about the missing signature, and finishes with following message:

Driver software was found, but an error occured while installation.
The device could not be started. (Code 10)

I checked the INF-file with ChkInf (WDK 7.1.0) on the target system and got only one error (no warnings):

Line x: ERROR: (E22.1.1081) Directive: CatalogFile required (and must not be blank) in section [Version] for WHQL digital signature.

I do not think this error is the reason for Code10.

I furthermore checked the usbser.sys on the target system. It's version is 6.1.7600.16385.
It's date is 14.07.2009 02:06.

I do not know what to do now to make the driver work.

Finally, here is my revised INF source:

Has anyone hints for me to solve the problem and make the port work?
