ASI462 does not work with ASIAIR v1.4.4, and my ASI462 had also been sitting idle for almost a month, since I am pretty much exclusively using ASIAIR nowadays.
In the past day, I have been running a pre-public Beta of ASIAIR, and I can confirm that the ASI462 is working in the v1.5 version of ASIAIR on iOS.
Just wait for the public Beta to be released (monitor the announcements on ASIAIR Facebook page), or wait for the real v1.5 release if you prefer not to test Beta software, which potentially has bugs with the less common functions or devices.
