[Ti] Early morning scare...

[Jim Soriano]

Some USB hub chipsets are more susceptible to low voltage conditions 
than others.  This is a fairly well-knows issue with engineers that 
design the creatures; I'm surprised that the power margin on the Studio 
Display seems so slim.

Anyway, it's another thing to add to your troubleshooting list -- if 
one or more USB peripherals exhibit flaky operation, 9 times out of 10 
its a low voltage condition at the hub (in my case, it means I've again 
kicked the wall wart power supply out of it's socket.)

Best regards,

Jim
