Did you try with lsusb and dmesg?

They should show if the Arduino was detected and what are its parameters (use lsusb -v for more detailed info).

If it is detected but you do not get the corresponding tty device, it might be because of missing/different rules.

You could check out this link and edit the parameters idProduct and idVendor to match what you get from lsusb, in case your rule is not matching.

Then remember to reload the modified rules.

Protip: compare the parameters of your working Uno against the ones from the Nanos and the values set in the rules.
