cannot mount my usb memory stick

jbcolmena · 09-07-2006, 10:37 AM

Hi everyone!

About a week ago I installed Slackware 10.2 (full install). After some trouble -was not able to mount my cdrom and hotplug would cause trouble at booting- I got everything working -almost-. To do this, I installed the 2.6.x kernell that comes in the second cd. note: my linux box is about 5km away, and I don´t remember with exactitud some things. Sorry. I followed the instructions giving in the cd, and basically did this: pkginstall the kernell and kernell modules, change lilo.conf pointing now to my new kernell. Since I´m using ext2 filesystem, I understood that that was all. It so apears, because everything went smooth, but for this: I cannot mount my usb pendrive. When I try "mount /dev/sda1 /mnt/hd" I get a message that says something like "/dev/sda1 is not a valid block device"

So I´ve doing some reading and searching, and have found some sugestions to people who has had the same problem. I give the answers to this sugestions:

dmesg: when I plug -or unplug- the pendrive, dmesg does not says anything. As if nothing had happend.

fdisk -l: when the pendrive is in, it does not appears on the list.

modprobe: I went trough the rc.modules file (a file located in /etc/rc.d) and check out modules for usb massive storage (again, sorry if the name if not exact. Next time I will write everything down before writing the post) and it works, or so the system says when booting. But for things like usb-hid and similar modules, I get a message like: module does not exists.

I know the usb ports are connected. When I put the memory sticks in, the light flasesh. Neverthless, it´s as if the usb didn´t exist at all!

Don´t know what to do, and I´ve been reading all the HOWTO´s I was able to find and looking all over internet, but to no avail.

BTW: when I say : "mount /dev/sda1 /mnt/hd", I mean I´ve tried /sda2, /sda3... /sdb1... /sdf3.... yes, sound crazy, but I´m runing out of ideas!

Any help would be appreciated. Thanks!

Hi there, welcome to Slackware!
I'm wondering if you installed the modules for the 2.6.x kernel as well.
Those are also found in the second cd.

Post any thoughts that you have

Yes, I installed the modules that were on the same directory as the kernell 2.6.x.

check lsmod and review if there is USB support loaded, my lsmod output looks like this:

If you don't seem to have loaded any of those modules that I marked, modprobe one of these USB modules:

ohci-hcd -- for non Intel or VIA based systems
uhci-hcd -- for Intel or VIA systems

and check what happens on lsmod and dmesg

Thanks a lot!

That solved the problem.

Now I can get back, and enjoy my box.
