How does one get Linux (SuSE 9.0) to find devices connected to an 
external USB hub?

When I plug my printer, Palm device cradle, scanner, etc., directly into 
one of the USB ports on my computer I can access them. But when I plug 
an external USB hub into the port on the computer and these devices into 
that hub I cannot find them.

I suspect I need to do something to activate the external hub itself, 
since it is not lighting up like it does when I am booted into  WinXP...

TIA for your help!

God bless!
