As dfrey noted, could be a dead port.
Could also be a bad cable from CF3 to PC.
Could be bad CF3 connector.
- Try David’s suggestion first.
If that doesn’t work:
- Remove cable from CF3 USB connector
- Remove cable from Console USB connector (we’re going to use this one in a moment, because we know it’s a ‘good’ cable)
- Move jumper on power header to the pair of pins closest to the battery connector. (this selects CF3 USB for power supply)
- Connect the cable to CF3 USB (make sure it’s seated correctly) and to the PC.
Did the Power LED come on? If not, then the connector seems to be dead. Disconnect and try again (making sure it’s seated properly).
If the power LED does come on, then see if it’s enumerating on the PC.
If it is, then the problem was either the cable or the cable not sitting properly.
If it’s not enumerating… let’s cross that bridge when we come to it
