It's the same whether I use my Mac or my Windows machine (I'm trying to set it up so I only use the Mac for both). Freshly updated Calibre on both, so 8.2.1, but I saw the same thing the first time I tried this maneuver, back in the 7.x days. So I don't think the OS or Calibre versions are relevant here.
Where does KU get the serial number from when it first sees the device, and where does it get the serial number from when it does a database backup? If those are different, that would be a big clue toward figuring out how I fouled up.

I think the problem is that by copying the contests from the old device from the new one you also copied the file 'driveinfo.calibre' which Calibre uses to identify devices, which means that now both devices look like the same device. As I understand the code at the moment the current best way to fix this should be this:
- Remove both devices from the Devices tab.
- Remove the file 'driveinfo.calibre' from the root directory of both devices.
- Eject and re-plug the devices (this may be optional but can't hurt).
- Re-add the devices in the Devices tab.
There is an
open issue about changing the device matching so that this situation shouldn't happen again, but I need to find the time to implement that first.
