Ok, it's time to dive in. Do you know UsbView.exe? It's here: https://www.ftdichip.com/Support/Uti...crosoftUSBView
Figure out which location on the left side of the screen which is your port.
Just plug/unplug whatever and look for changes.
Make your Lumi go to fastboot.
Look in the right side of the screen for Class/Subclass/Protocol of ff/42/03 that's fastboot.

Code:

Interface Descriptor:
bInterfaceNumber:     0x00
bAlternateSetting:    0x00
bNumEndpoints:        0x02
bInterfaceClass:      0xFF
bInterfaceSubClass:   0x42
bInterfaceProtocol:   0x03

Then look up at the top:

Code:

Device Descriptor:
bcdUSB:             0x0310
bDeviceClass:         0x00
bDeviceSubClass:      0x00
bDeviceProtocol:      0x00
bMaxPacketSize0:      0x09 (9)
idVendor:           0x18D1
idProduct:          0xD00D

Edit: And it should also say this:

Code:

Open Pipes:              2

Check the VID/PID (idVendor/idProduct). Do they show up in UsbLog nice in green?
If not, find it in Zadig and load a new driver.
Does fastboot getvar all work? (It should spit out 100 lines).
