8 years agoAltera DE0 Board not detected by Windows
Hello everyone.
I am having a problem with my Altera DE0 board and I couldn't find anything to help me out. My board was functioning normally. Some days ago it completely stopped working with Windows. Windows does not detect my board when I plug the USB blaster cable in my notebook. The "usb device connected" sound does not happen. But, if I plug the USB blaster cable to the USB and the FPGA, without using the power source cord, my board powers up normally. The usb cable works like a power source. The problem is, since this happened, I cannot program anything. Windows does not recognize my board. Softwares and board I use: Windows 10 x64 Quartus II 9.1sp2 Altera DE0 board (not the nano) What I have tried so far: Plugging the board to another computer: no "usb device connected" sound; USBdeview: nothing related to the board appears; Removing the Altera USB-Blaster from device manager: I uninstalled the driver from device manager. Now, windows doesn't detect my board and there is no "installing new driver" when I plug the board to usb. What I think might have happened: One day I accidentally turned the board on only using the USB-blaster cable, with no power cord from the source. After this day, my notebook stopped recognizing the board. Anyone knows any solution to this? Thanks. (edit: ) Now I also tested: ->New cable: no response; ->Installed ubuntu 17.04: used "lsusb" and "lsusb|grep Altera" commands, getting no response from the board; ("lsusb" lists all usb devices connected to PC and "lsusb|grep Altera" lists devices with Altera name on it) -> Reinstalling quartus II 9.1sp2 and still nothing.
