I am trying to use my old Flotilla kit on my new 4Gb Pi4 under Buster. I edited the install file as advised elsewhere on the forum and this seems to run ok - well, rockpool appears in my menu at least. However, when I connect the hub, rockpool shows two hubs (???) and says they need to be updated. When I click on the active “update” link it takes me to the “getting started” page, but none of the apparently active hotspots on that page are actually active, so the process ends there! Also, which may be unrelated, connecting the hub renders my wireless mouse inoperable, removing the hub restores the mouse, but I’ve reverted to my old cable-connected mouse for the time being.
