Issue with installing driver on Windows 7 64bit. Name is already in use.

Hello,

 

I have been attempting to install a driver for the HiTech Global Virtex 6 USB 2.0 port. The Virtex 6 uses CY7C67300. 

 

  1. I restarted the PC and disabled driver signing
  2. I installed Cypress 3.4.7
  3. I copied cyusb.inf and cyusb.sys from wlh\x64\ to C:\CyInstall\
  4. I modified the VID for 04B4 and PID for 7200 (see attached cyusb.txt for the exact inf file)
  5. I connected the device and it failed to install (it was detected as an unknown device with no driver)
  6. I browsed to C:\CyInstall and selected cyusb.inf and continued with the installation when the warning popped up about the driver not being signed.
  7. I then get the error "The name is already in use as either a service name or a service display name."

 

I tried to debug this issue by looking things up on the web and found that this typically means something was left behind from the last install (I tried a few times previous to this attempt but failed). I then uninstalled cypress 3.4.7. I deleted all cyusb.inf and cyusb.sys from System32. I deleted a registry entry I found in HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Setup\PnpLockdownFiles that had cyusb in its name. I deleted the oemXX files that contained data for the VID 04B4 and PID 7200. I then disabled all non-microsoft services and restarted the computer.

On reboot I did the same thing I did above and encountered the same issue.

 

What am I doing wrong? I have followed the manual exactly and I just can't get the driver to install properly.

Have you modified the strings in Strings section at the bottom of the page?

The service name added for handling device would be assigned a name through the inf file. Have you tried changing that (this needs more modification and has to match with other sections of the inf file).
