Unhappy USB + Modem + Slackware 8.1 = No Working

hello all i really hope hat someone can help with my dilemma i have a usb speedtouch modem which works fine under SuSE (im coming from suse onto Slackware, i really find most distro's quite bloated) i installed slackware last night but i cannot get my modem to activate (i.e. the lil lights turn on ) under SuSE it is automatically detected and on boot up it is activated which is all well and good.. while in SuSE i noted which of the Kernel Module had been loaded and wrote them down. When i booted into slackware i performed the following steps

modprobe usb-core
mount none /proc/bus/usb -t usbdevfs
modprobe usb-uhci (i also tried modprobe uhci)

if i turned off hotplugging in SuSE the usb modem would not get activated at boot up but if i ran the following commands it would so then id be able to use it..

In Slackware it just sits there lukin somewhat pretty, i looked at /proc/bus/usb/devices and it is recognising the hubs are there but it is not finding the devices attached to it (i have a mouse on it too but for the time being its just on the ps/2 port)

Does ANYONE know how to get this working? i really like slackware its much less bloated than the others i.e. SuSE/RedHat (havnt tried Debian or Mandrake (i woz told mandrake is pretty much like SuSE so it put me off)

Just to point out i liked suse and i even had 7.2 for a long time but SuSE8 is tooooooo much

Anyway HELP

Depending on the default kernel you loaded will guide as to what modules might be needed to provide usb support. To list what modules are actually loaded use the "lsmod" command.

For a non-usb enabled kernel like bare.i,

modprobe usb-uhci (or modprobe usb-ohci)
mount -t usbdevfs none /proc/bus/usb

The modprobe command above should autoload the module usbcore. Also, there is a uhci module. Not sure what the difference is with usb-uhci though.

For a usb enabled kernel like usb.i, then just

mount -t usbdevfs none /proc/bus/usb

Either should mount your usb file system so that

cat /proc/bus/usb/devices

will produce output. Allbeit difficult to read. But the lines that start with "T:" I believe identify a new item. Also, I have found the output from the command "dmesg" of great help as well. If you plug and unplug the device a message is usually added to the end of the output.

SuSE could have other addin modules as well that are not part of the standard kernel support. Also, SuSE 8.1 is based on the 2.4.19 kernel and it has considerable more support for USB and Firewire devices than the 2.4.18 kernel does in Slackware 8.1. Also, do you know what module SuSE was actually loading for the Speedtouch?

For your mouse, a usb enabled kernel should support it, and on a non-usb enabled kernel after uhci (or ohci) support is loaded;

modprobe hid (or modprobe usbmouse)
modprobe mousedev

That should also autoload the module "input" as well. The mouse is normally on /dev/input/mouse0. If want to set the default device, /dev/mouse, to it then;

ln -sf /dev/input/mouse0 /dev/mouse

You didn't state the type of modem the Speedtouch is. But when I searched the only references I could find are for a ADSL modem. Now if your unit is an ADSL modem then you might want review the following link for some driver information.

and there is an ongoing project here;

Perhaps it will be of some help.

Thought id get back to you... i done as stated and it still didnt work.. in the meantime i did download the linux kernel 2.4.20 (while in windows) and compiled that kernel with extra usb module support and it works but only if i load both the ehci (USB 2) and the uhci modules its quite bizarre it will only blink if both are loaded... nvr mnd it works now... now just the task of upgrading gnome n the like

Thanks Again
