Hello,
after inserting my huawei usb modem and using usb-modeswitch, the number of udevd is increasing from 3 to 12. I think this is too much. It should be maximum 4. Is it right?
What happens here? Is there an issue?
My impression is too much udevd will use RAM/cpu.
-
The extra udev processes should die down after a while. Unless they actually start hogging cpu, nothing to be concerned about.

Yes, udev spawns multiple processes to handle events better.

yes.
Only 12 for me...;-) (I could not post the screen copy because the size was too big. How do you have posted this ? would be good to know)
Looks a bit like a mess in TOP.

Hi floppy
Start top, click the button in the title bar to make the window tall. Move the mouse cursor to where you want to
start copying, hold down the left mouse button and drag the mouse to highlight what you wish to copy. Move
to where you want to copy to, left click to position the cursor, then center click to paste.
