Cannot mount usb anymore (/dev/sdb doesn't exist)

samuele.mattiuzzo · 2010-02-05 09:45:30

Hi!
I modified rc.conf and rc.sysint and everything works fine, except i cannot mount usb drives! lsusb shows them, usb ports are working (i'm using a usb wireless mouse, and it works without any problem)

this is my rc.conf

# MOD_AUTOLOAD: Allow autoloading of modules at boot and when needed
MOD_AUTOLOAD="no"

If you turn this off, you wll have to load the modules you need manually - usb-storage, in this case.

samuele.mattiuzzo · 2010-02-05 11:14:16

yup, thanks! that solved

dcc24 · 2010-02-06 11:06:38

I was having the exact same problem and adding usb-storage to the modules array solved it.

Still, I've used "hwdetect --modules" to generate that list, shouldn't it automatically include usb-storage?

<offtopic>Please mark the thread as [SOLVED]</offtopic>

Mr.Elendig · 2010-02-06 13:33:46

Only if you had a usb stick plugged in when you ran it. (not to mention that hwd/hwdetect is not reliable at all)

trusktr · 2010-02-21 00:23:15

hey guys, if you don't see your USB devices, it could just mean your system doesn't know what to do with them, but it knows they are there. you can see connected devices with lsusb.

I was happy to see my devices were connected. The thing is though, gnome doesn't come with any type of interface to show you if anything is connected.

I guess here enters "usbview"... I installed it, but it is not working at all.

When i plug in a flash drive (that i just found, hehe) it pops up on the desktop and a browser opens. But when I run "usbview" the window opens, but no devices are shown and it comes up with an error:

USBView Error
Can not open the file /proc/bus/usb/devices
Verify that you have USB compiled into your kernel, have the USB core modules loaded, and have the usbdevfs filesystem mounted.

How can I verify the suggestions the message gives?

na12 · 2010-04-11 19:22:18

I have the same problem,Dmesg output show that usb is connected
