MCB1700 virtual comport problem on win7

 MCB1700 virtual comport problem on win7

Hi,
I couldn't install the virtual comport driver given by NXP (USBCDC project) on win7.No problem on XP.
Is there anyone run USBCDC on win7 ?
Has anyone experiences about this subject?
Where can find a suitable driver for win7 if there exist?

I am waiting suggestions asap.

Thanks.

Hi,
Ok. I am in trouble. Please help me to modify and run CDC example on windows7.
Is there anyone have already done it?

Not sure, but maybe see this:

 RE: MCB1700 virtual comport problem on win7

I did not see significant differences.
If there is someone running it on win7 with this INF, please inform me. Thus, I can search problem elsewhere.

Thanks.

> I did not see significant differences.

Ah, you can see the significant difference, but you don't know what it is. ;-)

The error lies in CopyFiles directive on [LPC17xxUSB.nt] section

[LPC17xxUSB.nt]
include=mdmcpq.inf
CopyFiles=DriverCopyFiles   ; <------ wrong one, reference to a section of THIS INF

As CopyFiles references to the section of THIS INF, [SourceDisksNames] and [SourceDisdsFiles] of THIS INF is applied. In your case, both sections are empty. "include=mdmcpq.inf" line is vain, because you refer nothing from mdmcpq.inf.

The right one is,

[LPC17xxUSB.nt]
include=mdmcpq.inf
CopyFiles= FakeModemCopyFileSection   ; <------ right one: reference to a section in mdmcpq.inf

When CopyFiles references to "FakeModemCopyFileSection" derived from mdmcpq.inf, [SourceDisksNames] and [SourceDisdsFiles] declared in mdmcpq.inf is applied. mdmcpq.inf points the right place of original usbser.sys location in [Source...] sections



There is no difference on the CDC (usbser.sys) INF file among Win XP, Vista and 7
The major difference lies in the pre-installation of usbser.sys to the driver folder on each PC.

Most of Win XP still have usbser.sys installed in the driver folder,
But for Vista and 7, usbser.sys is not installed there, but held in the installation archive (such as I386 folder).

MS has warned to us not to reference usbser.sys location directly on our custom INF file (*1)
Instead, they suggest to "include" mdmcpq.inf AND reference to "FakeModemCopyFileSection"
because mdmcpq.inf knows the right place on which the original usbser.sys exists.

Just writing "include = mdmcpq.inf" does nothing. Reference to the section on mdmcpq.inf correctly.

You are absolutely right :) I will try to run it in a few hours and inform you.

Thank you.

Hi,

However, I got the error message " Windows was unable to install your ST VIRUAL COM PORT"

Tsuneo, Could you please help me to figure out the reason?

Thanks a lot for your help.

Hi all,

More infomation for my scenario. My machine is 64 bit Windows 7. I run the command " bcdedit.exe -set TESTSIGNING ON" in the command prompt and make the windows go to TESING MODE. However, I still get the same error message.

I greatly apperiate any suggestions.

Finally, the driver is installed under WINDOWS 7. I add the part NTamd64 in the inf file.
