Probs mounting USB-device

Malycha — Thu, 05 Sep 2002 05:36:21 GMT

Hi all!
Some days ago I bought me an ARCHOS Jukebox Recorder for usage on journeys. My OS is SuSE-Linux 7.3 (kernel 2.4.10) on an HP OmniBook 4150b (P3/650). Now my problem: When I boot the system with the JB connectet ther's no problem. But when I connect it during work it is not always recognized.

The USB- and SCSI-support in the kernel is activated.

Does anyone can give me an advice

I'd note which kernel modules are installed when the device is working properly (lsmod) and then, if SuSE doesn't auto-detect it when it is hot-plugged, you can insert the particular module that configures the device manulally (modprobe). I do this with my flashcard reader all the time.

Hello,

SuSE implements the USB hotplug using the "usbmgr" daemon.
In /etc/usbmgr, there are 2 configuration files :

=> "host" contains the USB driver to be used (usb-uhci or uhci or ohci or ehci).
Leave this untouched.

=> "usbmgr.conf" specifies to the usbmgr daemon information about which kernel module(s) to be loaded after a USB device is plugged.

For example to make my CD-Writer recognized, I had to add these lines :

# CD-Writer Plus 8220e/8230e [HP]
vendor 0x3f0 product 0x207 module scsi_mod, sr_mod, usb-storage

To obtain the vendor and product IDs of your JB, have a look in /var/log/messages or check "/proc/bus/usb/devices".

At last, make sure that usbmgr is automagically started at boot. In /etc/rc.config : START_USB="yes"

Good luck.

I found a solution on my own:

This link may help - on my OB4150b now it works!
