Oh the dream of connecting 127 devices at once! It'd be a dream if I could connect even…say..more than four…
I have a Belkin USB hub with 7 ports on it. At any given time I can get about four of them to work. (Actually, all the ports work, just not all at the same time…)
Could this be somekind of a memory issue? I have a teribyte-and-a-half hard drive hooked up to it, and when I plug in my measly 8GB thumb drive it doesn't recognize it and I have to plug it into a port directly on the machine to get it to work.

As an insult to the existing injury...each hub counts as a device, so you'll burn quite a few device addresses on your quest to get to 127.
A "powered hub" actually has a power supply that plugs into it. A lot of them are made this way.
If the hardware conforms to USB spec, and the operating system is decent, you will get message pop-ups for actual faults. If the current draw is too much you would get "power limit exceeded" message. If a device just stops responding there's no message, but there is that "disconnect sound" if you use Windows.
A lot of those "USB toys" made overseas patently ignore anything about power requirements. They also work a lot of the time, which tells you how faithfully most computers follow the spec.
