USB devices always "on"
Now this is plain weird.
I have an acer athlon 64 PC with suse 10 X86_64 loaded in.
A bunch of USB devices are connected: mouse, keyboard, joystick, webcam.
When I shutdown the machine they stay on: I see the red light under the
optical mouse and the blue light on the webcam even when the PC is off.
When I boot into XP they correctly turn off when the machine is stopped.
Does anybody can explain why is this thing happening?
Another not strictly related question: I have this USB webcam running
(Logitech STX Communicate). Driver spca5xx (compiled by myself) loads
properly at startup but webcam cannot be accessed (dmesg shows this error
"DEALLOC error on init_Isoc". I have read this is something tied to USB
bandwith saturation. Again no problem at all in XP though all USB devices
are connected to the same bus.
Thank you for your help.
