Honored ContributorHi Michele,
--- Quote Start --- Thanks for your answer, i installed windows Xp but when the operating system identify the device told me that is an USB <-> SERIAL. So i try to install driver but the S.o. say that the file didn't contain any information about installation of DE1. consider that i have a normal usb-cable NOT USB-BLASTER. --- Quote End --- If the FTDI FT245B device was somehow erased, or not programmed correctly, then it will show up as a USB-to-Serial device. Where did you obtain this board? Go to FTDI's web site and download their FTDI programmer (FT_PROG); http://www.ftdichip.com/support/utilities.htm Then ... 1. Run the program and select "Devices->Scan and Parse". It should detect an FT232/FT245 device with a blank EEPROM. 2. Select the device, and right-click, "Apply Template->From File", and select the attached .XML file (rename it before using it). 3. Right click and select "Program Device" 4. Right click and select "Cycle Port" This will program the FTDI device on the board, and then "reconnect" it to your PC. It will then be detected as a USB-Blaster, and assuming the MAX CPLD is still programmed, the USB-Blaster drivers should work correctly. If the XML does not work for some reason (FT_PROG's format changes depending on the version), then the information you need to manually enter prior to programming is; USB Device Descriptors: Custom VID/PID Vendor ID: 0x09FB Product ID: 0x6001 USB String Descriptors: Manufacturer: Altera Product: USB-Blaster Serial: BLASTR01 (or whatever 8 character string you like) Cheers, Dave
