Optimistic, ain't ya? The manufacturer's website is usually much less helpful than Usenet.

This is a little weird. I did "emerge --search hotplug" and found only 2 packages matching; sys-apps-hotplug and sys-apps-hotplug-base . The hotplug package creates an executable calledsbin-hotplug with config files inetc-hotplug. I don't know where these people got "usb-hotplug" from, since there's no package by that name on freshmeat.net or sourceforge.net .

All hotplug really does is detect when a new device is inserted, then modprobe the proper module for that device if the proper module isn't there. If you've modprobed usb-storage, uhcihcd (or whatever is appropriate--use "lspci -v grep HCI" to find out), srmod, sg, and scsimod before the CD-RW is plugged in, it should work and you should see it in "catproc-scsi-scsi".

A bug no clue what causes this
Hello, I was playing with pivotroot(8) chroot(1) in the last couple of days, and I found an abnormal behavior regarding the fd redirection...

Try making sure the USB CD-RW is powered on before you plug it in. I had a USB Archos 6000 that had to be fully powered on before you plugged it in to any USB host, or it'd sit there and sulk instead of being a USB storage device.

Another thing to do is to make sure that the module for low-performance USB storage devices isn't loaded. I forget what that module's called, but it probably has "ub" in its name, and a number of people have reported on Usenet that it's caused them problems. Those problems went away when they did rmmod on that module.

There is no usb-hotplug kernel module AFAICT. USB is designed to be hot-pluggable, and eouhcihcd are all supposed to support devices being plugged-unplugged at any time. pcihotplug exists because there are some (expensive) machines that support hotplugging of PCI cards.

If it's not on freshmeat-sourceforge, you'll probably have a difficult time finding it. Googling "usb-hotplug" turned up a problem with Redhat-Fedora, USB Mbutt Storage devices, and 2.6.10, but you're using Ubuntu, not a Redhat-derived thing. Another result complained of OOPSes with a USB serial converter and 2.6.7 on Debian, but you aren't having I could sit down with this misbehaving device, I could get it working in ~15 minutes. Sigh....
