USB hot unplug ( hotplugctl )
Hi folks,
Background
I have a JungSoft Muzio mp3 player, in SuSE 8.1 it was recognised and could be read from/written to; but after umount the device would still display the "usb connecting" message* , and after physical removal or power off it would report a corrupt file system (though it still worked fine, but would whinge about the corrupt fs whenever turned on).
* The mp3 player displays two messages "usb connecting" and "transfer in progress", the "usb connecting" message is always displayed when there's no transfer.
I now have a copy of SuSE 9.1 pro, and the problem has been reduced... now after umount it still displays "usb connecting" but if unplugged it won't report a corrupt fs. However when the device is inserted again it's not recognised...
As the main machine (holding all the music) in the house is on 24/7, i'd rather not have to reboot each time i want to unplug the mp3.
On a windows system after clicking some disconnect icon near the clock the device shuts down and starts up as a player, powering itself from usb - it can then be safely disconnected. No drivers were required for the afore mentioned OS, it operates as a generic mass storage device
Questions
Does anyone know if a specific usb device can be disabled/ejected?
i have the hotplug and autofs daemon running, could these cause this kind of problem?
i've tried using hotplugctl, but i can't find any documentation (suse manuals or web) to help identify what the hwid hardware ID is. Any ideas?
thanks,
Caspar
