USB hot swappable?

[Nobody's Hero]

Anytime I hot swap a USB device, I lose sound on my computer. Is it a bad idea to hot swap USB devices?

I have an iBook (800 MHz G3, 14 inch, combo drive, 384 MB RAM) running Yellow Dog Linux 3.0.

USB devices I commonly use are a wireless mouse, wireless keyboard, and a notebook light (sometimes through a little four port hub, sometime not).

I use my laptop both at work and at home, and unfortunately sometimes when I plug in one of the devices it "wakes" and then plugging in the rest of the devices makes me lose sound. I just about always have OGG files playing in the background when using my computer, so I always end up restarting. Anyone else have similar problems? Is there anyway to get sound back without restarting?

did you try using "rmmod" to remove the sound driver and then "modprobe" it back into memory?

I tried modprobe -l \* and see that emu10k1 is loaded. But if I type in rmmod emu10k1 it says that it isn't loaded. I'm doing this as root.

modprobe -l \* only lists the modules you CAN load. lsmod will show what is loaded.

Yeah, I realized that after I posted., sorry.

That doesn't work though. It won't let me remove any of the sound modules because it says they are in use.

Also, I've noticed that when I leave my mouse and keyboard plugged in when I put the laptop to sleep, when it wakes i can use the mouse but not the keyboard.

Is there some safe way of adding and removing USB devices without all these problems? How do I reload my USB devices?
