Hello everyone,I'm trying to get DE2_NIOS_DEVICE_LED demonstration working. The problem is when I try to install the d12test.inf driver, windows says "the wizard could not find a better match for your hardware .... " and the Philips smart evaluation board is not installed. ------------------- Step 9 of README.txt 9) Run the project on the board. (Run menu) I choose "run" from the upper toolbar. Then I choose "Nios 2 Hardware", then "new configuration". I select project "hello_led_0". JTAG cable: automatic JTAG device: automatic Nios 2 Terminal: jtag_uart_0 At this point the only wires connected to the DE2 board are: "blaster" and "DC 9V". I click "run" from the nios 2 window. From the terminal: nios2-terminal: connected to hardware target using JTAG UART on cable nios2-terminal: "USB-Blaster [USB-0]", device 1, instance 0 nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate) disconnect disconnect connect_USB CONFIG CHIP ID =0x3630 --------------------- Step 10 of README.txt Now I connect "DEVICE" wire from DE2 to USB on my computer. Immediately Windows says "USB Device Not Recognized". Nios 2 Terminal outputs this: CHIP ID =0x3630 SUSPEND CHANGE SUSPEND CHANGE BUS RESET disconnect connect_USB CONFIG CONFIG .. repeat above 7 lines .. --------------------- Step 11 of README.txt Since I am on a windows machine, I go to Device Manager. Under "Universal Serial Bus" controllers I see "Unknown Device". This is probably the device that needs drivers since if I disconnect the DEVICE wire, this "unknown device" disappears. I choose update drivers.. install from specific location... "include this location in your search".. I choose the path which contains d12test.inf (there are actually two folders that contain this, both resulted in the same error). I click next then hardware update wizard says: "the wizard could not find a better match for your hardware". If I choose "don't search. i will choose the driver to install" and choose d12test.inf .. same error. If I right click d12test.inf and choose install, nothing happens (philips device is not discovered). -------------------------- For all cases, the program isp1362dcusb.exe outputs 0x0 no matter how many times I press add. I'd appreciate all comments and advice. Thanks!

Dear Friends,I also had a similar experience.I could not install the ISP1362 river for one month. I solved the problem recently. You try connecting both USB cables( Blaster and Device ) from the begining. Also do this while building the project.after build is complete rmove the USB cable from Device port aand run the C program, once u get a message chip ID XXX, u connect back the Device USB, your DE2 board will be detected by the OS as a new device and it will prompt you to install the driver. I hope this will help you... Regars, Mahesh

Dear Friend,I solved this problem by using 2 USB cables. Before you programming to DE2 board, you make sure 2 USB cables (USB blaster and USB device) to connect your host computer. It will be solved your problem Regards TZ
