修改FT232 USB PID

 問題: 

使用FT_Prog修改FT232R PID = 6002/6003/6004 (原始 VID = 0403 PID = 6001),

Window無法正確辨認到FT232R, 而且FT_Prog也無法抓到FT232R, 因此使用FT_Prog無法回復PID = 6001

對策:

下載FT232R VCP driver (CDM v2.12.28 WHQL Certified.zip), 解壓縮後, 手動修改ftdibus.inf和ftdiport.inf並且重新產生*.cat

修改ftdibus.inf

此時手動安裝驅動, Window回應雜湊碼錯誤, 我們需要對修改後的INF產生一組新的ftdibus.cat和ftdiport.cat檔案

open cmd, Run as administrator

假設WDK路徑安裝在C:\Program Files (x86)\Windows Kits\10

cd C:\Program Files (x86)\Windows Kits\10\bin\x86

執行Regedit, 查看HKEY_CURRENT_USER\Software\Microsoft\SystemCertificates\是否存在mySelfSignedCert, 

1) 確定是之前手動加入的私人憑證mySelfSignedCert, 手動刪除mySelfSignedCert

2) 如果不確定mySelfSignedCert是否是之前手動加入, 後續的mySelfSignedCert須使用其他名稱替代

假設HKEY_CURRENT_USER\Software\Microsoft\SystemCertificates\,不存在mySelfSignedCert或已經手動刪除mySelfSignedCert

產生私人憑證

Makecert -r -pe -ss mySelfSignedCert mySelfSignedCert.cer

//Succeeded

加入私人憑證

certmgr -add mySelfSignedCert.cer -s -r localMachine root

//CertMgr Succeeded

此時可用certmgr.msc查看, 受信任的根憑證授權單位增加一個Joe's-Software-Emporium, 時間為剛剛產生

產生新的catalog files

INF2CAT /driver:c:\ftdi_vcp_drivers_modified /os:7_X86,7_X64,8_X86,8_X64,10_X86,10_X64

//Done Adding Additional Store

//Successfully signed: c:\ftdi_vcp_drivers_modified\ftdibus.cat

signtool sign /s mySelfSignedCert c:\ftdi_vcp_drivers_modified\ftdiport.cat

//Done Adding Additional Store

//Successfully signed: c:\ftdi_vcp_drivers_modified\ftdiport.cat

此時手動安裝驅動, PC將FT232R視為USB Serial Converter裝置 (此時, FT_Prog已經可以正確抓到FT232R),

再次手動更新USB Serial Converter驅動, PC將FT232R視為COM Port
