Usb wifi adapter problem

Question

I have a usb wifi adapter (Edimax EW-7612UAn V2) with its driver installed on my parrot system and my computer's pci is not compatible with parrot .The problem is parrot says both adapters are disabled when i use normal wifi and when I use airmon-ng the usb wifi adapter works well and the computer's pci ,of course, doesn't work. when putting my pci in monitor and my usb wifi adapter in managed mode, network manager removes both of them from the wifi menu although the usb adapter is not in the monitor mode.

In other words, parrot won't recognize both adapters if the main pci isn,t compatible or recognizable. so, what should i do to force parrot to use the usb wifi adapter only ?

@roaima parrot says that both adapters are disabled while the usb wifi adapter is compatible with parrot and it works well with airmon-ng in monitor mode — mohamed, Mar 07 '20 at 08:57

I found the answer.Using instruction here,I found that my pci uses "rt2800pci".I unloaded the module using the following command :

modprobe -r rt2800pci

It worked well and the usb wifi adapter started working,but this solution works only for one session once the computer reboots you will have to unload the module again, you can blacklist the module if you want the module to be unloaded all the time.
