USB Mass Storage not detected
Quote:
I followed directions on this site: http://www.linux-usb.org/USB-guide/c607.html#AEN609 (and a couple others that I can't seem to remember now) and I keep getting to the same point... No devices are every listed in /dev/proc/usb/devices. I did read one thread on this site that seemed to indicate to me that I am going to need to be compiling modules, but want to make sure before I go making things worse. Current contents of the drivers: usbdevfs hub usb-storage also the output from dmesg: usb.c: registered new driver usbdevfs usb.c: registered new driver hub usb-uhci.c: $Revision: 1.275 $ time 19:56:21 Jan 20 2005 usb-uhci.c: High bandwidth mode enabled usb-uhci.c: v1.275:USB Universal Host Controller Interface driver usb.c: registered new driver usb-storage and modprobe usb-storage 62336 0 (unused) usbcore 58860 1 [usb-storage] And this is where I scratch my head and go huhhhh? :newbie: |
What version of SW and what kernel? Are you using udev? With that info the right help will come.You can scan LQ tutorials hardware section for articles on usb/firewire hard drives and flash card readers to get you started. And at linuxforums.org there is How to mount usb flash drives in linux. Have fun.

What is the output of dmesg when you plug in the USB key? If it's recognised, it should be something like this:
Code:
root@sphritzs:/home/leon$ tail -f /var/log/messagesCode:
# mount /dev/sda1 /mnt/your-mount-point-here/ |
try modprobe sg
|
When I plug in the USB device, there is no change in dmesg (actually, the one I posted was with the device plugged in).
"modprobe sg".... Didn't know about the "sg" driver. I had looked at a couple of other modules related to scsi, but didn't know about that one. I'll give it a try when I get home tonight (at work right now). Just a little more history. I had backed up a bunch of data to a USB drive I borrowed from work (OS was basic install of 8.x), and wiped my hard drive. I haven't used a USB drive since, and then recently my boss asked me about this data. Fast forward a year and I have done a fresh install on that machine (Slack 10.x). So I took the drive home, plugged it in, tried to mount /dev/sda1... nothing. That was two weeks ago. |
Oops! Others already said this...Darn my slow connection....lol

try
Code:
fdisk -land then mount it Code:
mount /dev/sdc1 /mnt/usb |
my USB entry in fstab ;
/dev/sda1 /mnt/USBdrive auto user,rw,noauto 0 0 as root in /mnt i = mkdir USBdrive rebooted.....et voilą. good luck ps = i also uncommented the usb mass storage entry in /etc/rc.d/rc.modules |
I don't seem to have the sg module. Shouldn't that have installed with my installation (Slackware 10.1)? I will attempt to compile it over the next couple of days.
"fdisk -l" showed only /dev/hda1-9 and I've already uncommented the modprobe line for the usb-storage. It appears as though my USB device is not being detected at all. |
this thread helped me get mine working...

None of that helped. My device does not appear to be being detected at all. I followed all of the steps and the output from my dmesg only changed after hotplug restarts: usb.c: registered new driver usbdevfs usb.c: registered new driver hub Initializing USB Mass Storage driver... usb.c: registered new driver usb-storage USB Mass Storage support registered. uhci.c: USB Universal Host Controller Interface driver v1.1 usb-uhci.c: $Revision: 1.275 $ time 19:56:21 Jan 20 2005 usb-uhci.c: High bandwidth mode enabled usb-uhci.c: v1.275:USB Universal Host Controller Interface driver usb-uhci.c: $Revision: 1.275 $ time 19:56:21 Jan 20 2005 usb-uhci.c: High bandwidth mode enabled usb-uhci.c: v1.275:USB Universal Host Controller Interface driver uhci.c: USB Universal Host Controller Interface driver v1.1 usb.c: deregistering driver usb-storage usb.c: deregistering driver usbdevfs usb.c: deregistering driver hub usb.c: registered new driver usbdevfs usb.c: registered new driver hub uhci.c: USB Universal Host Controller Interface driver v1.1 usb-uhci.c: $Revision: 1.275 $ time 19:56:21 Jan 20 2005 usb-uhci.c: High bandwidth mode enabled usb-uhci.c: v1.275:USB Universal Host Controller Interface driver |
kavius http://www.linuxquestions.org/linux/...d_Reader_HowTo should get things going for you. Though it is for card readers it applies to flash drives and hard drives. Step by step. It's an LQ tutorial.

Sorry, for some reason I didn't notice your first post. SW 10.1, Kernel 2.4.29. I have since downloaded the code for 2.6.13 from the slackware site and compiled that. No help. Infact my sound card doesn't work... booo. Kind of ironic, since the data I am trying to get off the USB device are all of my music files <chuckle />. Fortunately, I backed up the 2.4 kernel so no worries there. I tried the link you suggested: no effect. After recompiling the kernel, and rebooting, I plug in the device and cat /proc/scsi/scsi. There are no attached devices listed. |
plug your usb key in, and as root in a terminal type

This one is totally meaningless to me....
