Could you bind the device successfully (Check out device manager)??? If not, try with following changes
1.Modify your .inf file for Windows 7.
You can find the .inf file for 64 machine at C:\Cypress\Cypress Suite USB 3.4.6\Driver\bin\wlh\x64 and for 32 bit is in C:\Cypress\Cypress Suite USB 3.4.6\Driver\bin\wlh\x86. Modify the files accordingly.
2.Turn off Driver Signature Enforcement.
You can turn off the Driver Signature Enforcement by rebooting the OS with "Advanced Boot Options (accessed via F8 on boot up)' Disable Driver Signature Enforcement".
