I flashed the arch image on the website on my Udoo QUAD. I succeeded in working with wlan0 with wpa_supplicant and nmcli; my dekart dk-38t worked with pcscd too. I did a pacman -Suy this morning and I updated all the packages. After that wlan0 disappeared and dmesg doesn't detect if I plug in/off my dekart sim reader.

Should I reflash the previous image?
USB seems to be broken since 4.8.x with Arch Linux ARM on the UDOO. I fixed this temporarily by downgrading to the last 4.7.x kernel using: pacman -U /var/cache/pacman/pkg/linux-armv7-4.7.6-1-armv7h.pkg.tar.xz In my /etc/pacman.conf I set this to prevent upgrading the kernel for now when upgrading the system: [options] IgnorePkg = linux-armv7 I originally reported the problem to the Arch Linux ARM forum but my post didn't get much attention so far there: https://archlinuxarm.org/forum/viewtopic.php?f=45&t=10926
