Wireless adapter Z-Com XG-703A doesn't work with WPA after reboot

Hello everybody,

Arch doesn't load kernel module arc4 during boot with usb wireless adapter Z-Com XG-703A. So WPA doesn't work and It can connect to only opened access points.

I found two work arounds but I don't know how to fix the issue completely.
1. Remove usb adapter and plug it in again (it causes arc4 module to load), then restart networking.
2. rmmod p54usb, rmmod p54common, modprobe arc4, modprobe p54usb and after that restart networking.

Could anybody help to fix the problem generally?

Does the p54common get loaded again as well when you do modprobep54usb?
If not, you might just put that into modprobe.conf blacklist.

If it does get loaded as well, there might be another wireless module getting loaded that perhaps does cause problems. You can check that with

mkinitcpio -v

now, or with lsmod after a reboot before your workaround.
