    Can not re-install cyusb.sys after modify .inf file


      I follow Cypress CyUsb3.sys Programmer's Reference  to change .inf file with no rename  CYUSB3.SYS.


      1. Locate the [Strings] section at the bottom of the CYUSB3.INF file.

      2. Change the quoted CYUSB3_Provider string.

      3. Change the quoted CYUSB3_DisplayName string.

      4. Change the quoted CYUSB3_Company string.

      5. Change the quoted CYUSB3_Description string.


      and I re-install this changed driver. but failed.

      And I want to re-install the Initial driver, but  failed.

      The software for this device has been blocked from starting because it is know to have problems with Windows.

      Contact the hardware vendor for a new driver(code 48)

      more information show as bellow.

      How can I do?
