Ok, so unless you want this elsewhere, I am going to post my testing/findings/questions here:
1. I saw in your instructions that this device can "talk to any other AirTalk dongle on the network." Can they not communicate to the other AppleTalk devices connected via Ethernet, etc, on the same network?
2. ADB power works just fine; my first test is via the second ADB port on my IIfx, solo device. I will attempt to chain it to multiple devices (maybe two keyboards, etc), later on.
3. For some reason, my first test with an AppleTalk ImageWriter II (why not try the most exotic test first???) seems to show that it is very, very, VERY slow - as I write this, five minutes have passed....and I think the ImageWriter has attempted to write one single line of pixels. I am not sure why this would be.
Some clarification: I have one dongle on the IWII via Phone Net and phone wire, powered via USB cable. The other is hooked to my IIfx, powered via the ADB port of the IIfx. The IIfx is hooked to the AirTalk device via the Modem port. I suppose I could rule out issues with the Phone Net boxes by using a regular serial cable. They are connected to my home AirPort wireless network.
- LED 5 blinks red on both devices after the sequence of green LEDs while the devices are transmitting/receiving: is this indicative of some sort of error?
Update: using a serial cable instead of the Phone Net boxes makes no difference.
