After pursuing the matter with Bluez' developers, it seems likely the problem was protocol non-compliance on the part of this particular mouse model (it doesn't reply to an L2CAP information request). The Windows driver, provided by the manufacurer, probably doesn't issue the information request, resulting in a faster reconnection.
