Hi,
I was looking over the USB-IF (Implementers Forum)
compliance testing spec yesterday and immediately
had several questions.
[http://www.usb.org/developers/complian.html
and .pdf files from that page; and
http://www.usb.org/developers/complian_testing.html,
especially "Interoperability Guidelines" from
this page]
1. Has anyone tested bus-powered hubs instead of
self-powered hubs?
2. Has anyone tested 5 levels ("tiers") of hubs
and devices past the last level?
3. What's the most USB devices that anyone has
tested (at least connected) simultaneously?
There are lots of combinations that we could test.
I'm starting out easy. I'll bring a few devices
from home and scrounge some up at work next week
if noone else has tried these.
~Randy
