programmer doesn't see usb blaster

Hi all,

I had this problem now, everything had been working fine, but after PC restart, my programmer stopped to see USB Blaster.

I have tried everything you have mentioned here. Nothing helped.

1) Reinstall drivers - DIDN'T HELP

2) Reprogram EEPROM - DIDN'T HELP

3) Turn off firewall - DIDN'T HELP

4) Clean regs and temp files - DIDN'T HELP

My solution was restart of JTAG server.

1) Run CMD as administrator

2) go to \quartus\bin\ (if you are running 64 bit OS, go to bin64)

3) execute:>jtagserver --uninstall

4) execute:>jtagserver --install

5) execute:>jtagserver --stop

6) execute:>jtagserver --start

All these commands may help you to unstuck your JTAG recognition.

Good luck! I hope it will help someone. :)
