No, the Apple Wi-Fi/Bluetooth adaptors have leads that carry Bluetooth USB Data+ and Data-. Power comes from the PCI-e slot.
Not exactly true, some use 4 wire connections and some have 2 wire. 2 wire is data only. 4 Wire USB to internal can be voltage and data or fake and data only, however the exact voltge need is 3V and is not always handle right by components on the PCB. This is whay all most all the Chinese carrier adapters do not work in any slot other than X1. Backward compatibility for X16 is only true for the OSXwifi carrier, and the Wdxxfu Studio design (which uses a mini USB female slot on the PCB and correcponding cable). I have test the Fenvi but I tend to think it will nay slot as well. Asrock boards are the worst offenders for not working at all. Most of the carriers are crap other than these and your playing Chinese Roulette if you thing differntly. If you stick with X1 either with the real slot or a X1 extender cable you will have the best luck better than 50 50.
Any of the cards you mentioned should work in a PCI-e x1, x4, x6, or x16 slot since PCI-e is backwards and forward compatible in that regard. People have jury-rigged cards made for x16 to work in x1 slots by butchering the card or connector.
No jerry-rig on my part; It just is totaly not recognized as a wifi device at all, in my Z370 board, in any type of slot, but is fully functional in an Asus board.
Note the Fenvi Fv-T919 works. Its driver for Windows 10 on its Mdisk is not a Bootcamp driver its is from Asus so after installing it shows as Broadcom driver with a differernt version number and the card is seen as a BCM4360 as are both the 3 and 4 antenna versions the 3 antenna version being the newest with the wave form anntenna upgrade. The carriers for the 3 antenna cards are different part numbers, for the Chinese carrier suppliers, and even though the slot is the same, the voltage for Bluetooth and PCB is unique.
I am going to pull the 4 antenna card from the Chinese PCB carrier and mount it my OSXwifi Carrier which I know works, in both the Asus and Gigabyte boards. If the card is recognized this will prove it is not worth taking a chance on these unknown carriers to save a couple of bucks, if it works, you are lucky, if not, I TOLD YOU SO. I have been dealing with this mystery for a month, waiting for the Fenvi and now it does work, but I will not give up until I figure why the other 2 do not, in the
Gigabyte, but do in Asus, and Fenvi works in both and in any type of slot X1 or X16.
You get what you pay for.
