since I upgraded my RB3011UiAS-RM to RouterOS v6.45.5 it does not recognize the SanDisk Ultra Fit 128 GB anymore. Before I upgraded everything worked fine.
Then I downgraded to RouterOS v6.45.3 because this was the previous version where everthing worked. I applied the old configuration from the backup. But even back on the old packages version and firmware version it does not show the USB stick in the Disks list anymore.
I tried the USB stick on other computers and it's working fine. I also tried several different USB devices on the Routerboard but with no success.
What I'm doing wrong?
