Ya, I do admit to being perplexed as well. For all the troubles I've had with this, you'd think others would have had at least some problems as well (since lots of us jumped on that ebay deal), but I seem to be the lone voice in the darkness...whining away.
Of all the things I've plugged into it, the ALC/OnQ controller makes the most sense for not working. It seems to be really picky about timing and stuff like that. Heck, I've been having some issues with it connected to my native motherboard ports. But the other 3 items, the TRS RC-15, the Datanab 32i, and the Ocelot....
Well, I've certainly been doing my share of troubleshooting lately. Maybe this would be worthwhile to also see just what it is in my setup is causing these issues, assuming it is *NOT* the quatech box fault.
I think I'll pick a device (my RC15 really isn't be used much these days) and connect that to a box and see if its stable or not. And if not, I can start to try to figure out why.
One steady member of everything I've tried are these netgear switches and routers I have in the mix. Are any of those likely culprits?
