I have the same issue. After updating my Astroberry install yesterday, neither my Nikon D5500 nor my ZWO ASI120MM-Mini are detected by KStars/Ekos anymore.
What's particularly concerning is the output of lsusb:

astroberry@astroberry:~ $ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

At the same time, the cameras do show up in the dmesg log:

[ 2.051187] usb 1-1.2: new high-speed USB device number 3 using xhci_hcd
[ 2.182113] usb 1-1.2: New USB device found, idVendor=03c3, idProduct=120c, bcdDevice= 0.00
[ 2.182130] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 2.182146] usb 1-1.2: Product: ASI120MM Mini
[ 2.182162] usb 1-1.2: Manufacturer: ZWO
[ 2.281199] usb 1-1.4: new full-speed USB device number 4 using xhci_hcd

Not sure what's going on here, but maybe these logs help.
