Cyclone IV EP4CE10E22C8N is not detecting

Hello,

We are using Cyclone IV EP4CE10E22C8N. For this we are trying to program using only JTAG supported by USB blaster ver 2.2, in Quartus programmer it is not detecting. The same USB blaster programs Cyclone II using JTAG mode and also using AS mode with EPCS4.

We have made our Cyclone IV design as per given in Cyclone IV handbooks chapter number 8 “Configuration and Remote System Upgrades in Cyclone IV Devices”.

In that we have connected all MSEL pins to ground. DCLK and DATA0 pulled to Low. Pulled nCONFIG to high & pullups of TDI and TMS are 1K.

Device is not detecting, we are getting problem as below.

Please give suggestion on this.
