Mandrake 10 + usb hub


I have Mandrake 10 Official installed on an IBM ThinkPad T20 laptop. I have tried installing a couple of usb hubs (1 USB 2.0 and 1 USB 1.1). None have worked. I see others who have problems with freezing, I don't have that problem. Mandrake detects the USB hub, but doesn't know the module to use. How do I configure the module?

Anyone have success with this?

The device is a Dynex 4 port USB Hub (USB 2.0) Mandrake 10 sees the device as follows:
Vendor: ‎NEC Systems
Bus: ‎USB
Description: ‎USB2.0 Hub Controller
Module: ‎unknown
Media class: ‎Hub

I know there are 2 modules for USB, but not sure which one I need to use or how to configure. Any help?

I'm running MDK 9.1 and 10.1 (CE).
USB works just fine, although hotplugging is still a little weird.

Try lsmod as root to see what modules you have loaded.
For USB, I need:

usbcore
usb-uhci
ehci-hcd

So you could try (as root):
modprobe usbcore
modprobe usb-uhci
modprobe ehci-hcd

And then see if usb works. If it does, you'll want to make sure these modules are loaded at boottime.

Also sometimes Linux needs to see the external device powered up prior to the kernel load.

e.g. at boot or power on time

before it will properly detect a device.

Unhappy

It worked for a short-while...

I hotplugged the USB Hub (with a thumdrive attached),
su to root -->> lsmod -->> and the thumbdrive was mounted.

However, I plugged in my USB Harddrive and it has not been forgiving since. I did a cold boot with these items attached and nothing was mounted.

I tried the above modprobe's and nothing. They individually mount without the USB Hub...
How do I install the above modules into the kernel so they are available at boot?

Where to add modules for boot time depends on which kernel you are running. I use a 2.6 kernel so I use etc/modprobe.preload
It looks as follows:
# /etc/modprobe.preload: kernel modules to load at boot time.
#
# This file should contain the names of kernel modules that are
# to be loaded at boot time, one per line. Comments begin with
# a `#', and everything on the line after them are ignored.
# this file is for module-init-tools (kernel 2.5 and above) ONLY
# for old kernel use /etc/modules

As you see in my file it says if you use a 2.4 kernel, you would put your entries into etc/modules instead. By the way, this is to have the modules loaded at boot time, rather than just available when called upon.
