11 years ago --- Quote Start --- When I am in Linux, lsusb showed up with no changes whether I disconnected the device or not. As for windows, whenever I plug it in, it shows, "Unknown Device" in device manager. What is going on with my board? Is it a hardware failure? --- Quote End --- That does sound like a hardware issue. The general rule for hardware problems is; 1. Check power supplies 2. Check clocks So, go look at the DE-115 schematic and start checking the power supplies. Actually, in your case, first check the DE-115 with a different PC, just in case the one you are using has a bad USB connector. Cheers, Dave
