Re: USB devices doesn't appear

Not that I think it will help, but an interesting site for Linux and USB is http://www.linux-usb.org/

And the following text file describes how to add USB in fstab. I seem to remember that it was this way before, but I am not using fstab for anything USB related now? http://www.mjmwired.net/kernel/Document … b_info.txt

Might not hurt to try and add the usb system
Run the command as root: mount -t usbfs none /proc/bus/usb
Then load the usb_storage module again and see if that changes anything.

Re: USB devices doesn't appear

This is very strange. I have played around with some of the kernel modules in /lib/modules/2.6.32-ARCH/kernel/drivers/usb/, and loading them via modprobe always works, even if I have no related hardware on my system. For example:

[root]# modinfo cytherm
filename:       /lib/modules/2.6.32-ARCH/kernel/drivers/usb/misc/cytherm.ko
license:        GPL
description:    Cypress USB Thermometer driver
author:         Erik Rigtorp
alias:          usb:v04B4p0002d*dc*dsc*dp*ic*isc*ip*
depends:        usbcore
vermagic:       2.6.32-ARCH SMP preempt mod_unload 
[root]# lsmod |grep cytherm
[root]# modprobe -v cytherm
insmod /lib/modules/2.6.32-ARCH/kernel/drivers/usb/misc/cytherm.ko 
[root]# lsmod |grep cytherm
cytherm                 5659  0 
usbcore               140453  5 cytherm,usb_storage,uhci_hcd,ehci_hcd
[root]# modprobe -v -r cytherm
rmmod /lib/modules/2.6.32-ARCH/kernel/drivers/usb/misc/cytherm.ko
[root]# lsmod |grep cytherm
[root]#

Can you try some other modules and check if they are also affected (i.e. if they aren't loaded by modprobe), or if it is just usb-storage? Also, what does "modinfo usb-storage" show?

Good ideas do not need lots of lies told about them in order to gain public acceptance.

Re: USB devices doesn't appear

Well, that's also a solution.
Actually I also did that once because I couldn't get something (don't remember what) to work, and it worked for me afterwards.
Sometimes it's just quicker to start over.

Re: USB devices doesn't appear

I really didn't understood what was wrong, but now, everything works fine (just need a little more tweak )
