Running into the same issue on a new Spider board I just got. On one machine when I plug it in to USB, nothing happens at all on the PC (no USB connection sound, no indication that the PC sees the Spider at all), although the USB Client DP and the Mainboard LEDs both light up. Tried the firmware updater, but it can’t see the board, nor is the board showing up in MFDeploy.
On a second machine, I do get the USB connect sound, but it says that the USB device has malfunctioned and cannot be recognized. Tried uninstalling from device manager and plugging it in fresh…no luck. Tried firmware update from the 2nd machine, still could not see the board (and yes, in both cases, I set the switches for firmware update mode).
In all of my attempts, I’m connecting direct, no USB hubs, and I’ve tried both USB alone, as well as USB + separate wall wart to ensure there was plenty of power.
Any suggestions in terms of troubleshooting would be welcome.
