USB inf file can not pass the signature validation

Question

I'm trying to sign my USB INF file by Inf2Cat.exe command, but the signing result is always fail. The fail reason as below

Errors:
22.9.10: usbser.sys in [virtualcomcopyfilesection] is missing 
from [SourceDisksFiles] section in \tpp_test.inf;
driver may not sign correctly until this is resolved.

I used the instruct "Inf2Cat.exe /v /driver:%~dp0 /os:XP_X86,XP_X64" to sign the USB INF file, and the USB INF file as below.

How to fix this problem?

Answer 1

The statement

CopyFiles=VirtualCOMCopyFileSection

need to be changed as

CopyFiles=FakeModemCopyFileSection

And the statement

[VirtualCOMCopyFileSection] 
usbser.sys,,,0x20

need to be changed as

[FakeModemCopyFileSection] 
;USBSER.sys,,,0x20
