USB Flash Disk - Not Detected in File Manager

As a newbie in linux I found problem with USB afterr updating libusb libusb-devel following one of the advise to connect modem, my AAO 110 Linpus cannot detect USB flash disk (thumb drive).

When using lsusb shown detected as root (?). mouse, printer, and usb modem (when connected) no issue, everything work perfectly but not USB flash disk!

[user@localhost ~]$

following all possible forum and messages with such instruction:
mount -t vfat /dev/sda1 /mnt/usb did not give better result.

When check /etc/fstab shown per below --- I did not know what to do since I am new...
/dev/sda1 / ext2 defaults,noatime 1 1
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
#none /tmp tmpfs defaults 0 0
/dev/sda2 swap swap defaults 0 0

I did not put up dmesg result since so mess-up or I did not understand it :mrgreen:

Could someone help to advise?
Rest I am pretty happy with this AAO 8.9" linpus with all "improvement" and additional software such as vlc, skype, amarok, gimp, dia, xmame, open office etc.

Thx before, Alex Gemaraz

 

You could do a dmesg, then plugin the drive and do a dmesg again, and post the new lines.

--J.

 

To get my 'webcam' to work I go into My Computer and double click on it, it just takes photos as best i can tell.

 

WTF?

 

Japser, when do dmesg without USB flash disk, below is the end message:

aufs test_add:377:mount[7786]: uid/gid/perm /tmp/posixdir 500/0/0755, 500/500/0755

[user@localhost ~]$

After plug an USB, Kingston, below is the new end line:

aufs test_add:377:mount[7786]: uid/gid/perm /tmp/posixdir 500/0/0755, 500/500/0755

Note:

How to make it right --- really appreciate for advise. Thx, AG

 

Well, this:

Code:

mount -t vfat /dev/sda1 /mnt/usb

won't work; you're telling the machine to mount your internal SSD as a VFAT volume (it's ext2) at /mnt/usb (it's already mounted at /). Plus, I don't think /mnt/usb exists by default.

But you're most of the way there. Instead, do:

Code:

sudo fdisk -l

You'll see /dev/sda, your SSD block device, along with sda1 and sda2, which are partitions on your SSD, and then something else, probably /dev/sdb, which'll be the USB stick block device. It may have many partitions listed under it. (/dev/mmcblk prefixes will indicate SD cards; ignore those.)

Try to mount it with:

Code:

sudo mount -t vfat /dev/sdb1 /mnt/windows

(changing /dev/sdb1 to whatever your device name was from fdisk listing). Remember, put the 1 on the end to specify the partition as opposed to the block device. Also, are you sure the USB stick is FAT32? It probably is, but you're stating that explicitly by specifying vfat as the filesystem type in that command. Try without the "-t vfat" flag if you run into errors.

If that works OK and you can see the files on it (try

Code:

ls -a /mnt/windows/

to make sure it's actually mounted), then you can troubleshoot the automount issue.

My guess is, it's a permissions issue. You could sort that out by putting an entry into /etc/fstab that sets the permissions correctly.

 

The problem is no 'sdb" in my system, below is the fdisk -l:

[user@localhost ~]$ sudo fdisk -l
audit_log_user_command(): Connection refused

Disk /dev/sda: 8069 MB, 8069677056 bytes
255 heads, 63 sectors/track, 981 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

Device Boot Start End Blocks Id System
/dev/sda1 * 1 850 6827593+ 83 Linux
/dev/sda2 851 981 1052257+ 82 Linux swap / Solaris

Disk /dev/mmcblk0: 999 MB, 999292928 bytes
32 heads, 63 sectors/track, 968 cylinders

Disk identifier: 0x00000000

Device Boot Start End Blocks Id System
/dev/mmcblk0p1 1 968 975679+ 6 FAT16
[user@localhost ~]$

When type sudo mount -t vfat/dev/sdb1 /mnt/windows would give answer "is not valid block device"
[user@localhost ~]$ sudo mount -t vfat /dev/sdb1 /mnt/windows
audit_log_user_command(): Connection refused
mount: /dev/sdb1 is not a valid block device
[user@localhost ~]$

Thanks for all advise - a newbie of linux, AG

 

Mattytee, just additional info, when do lsusb it will still detect --- for this exercise with 2USB drive, old one FAT32, 256 MB and new one FAT32, 2GB both is Kingston.

Sudo fdisk -l still not give any sdb... thx

[user@localhost ~]$ lsusb

My logic is: as long as the output of dmesg does not look any better there is nothing to mount.
Being a drive the module usb-storage should take care of this device and that does not happen.
( note: showing up in lsusb only means that the device identifies itself, nothing more. )
In your first line sou say:

My suspicion is that in order to get the modem to work you have disabled usb-storage.

Actually it picks it up, but then disappears again ( in the last line ):

--Japser.

 

All,

Just to close something that I started and might someone help with comments.
I can solve easily by deleting usb_modswitich (http://www.draisberghof.de/usb_modeswitch) and all files I created then the USB working per normal but not my modem (ZTE MF620 3G USB Modem) anymore :cry:

I did not know how or I might do wrong but the only thing I can do is USB working not the modem or the modem not the USB...

Basically below is the guide according to many website/blog:

Make the rules /etc/udev/rules.d/15-zte-mf620.rules

# cat /etc/udev/rules.d/15-zte-mf620.rules
ACTION!="add", GOTO="ZTE_End"

SUBSYSTEM=="usb", SYSFS{idProduct}=="2000",
SYSFS{idVendor}=="19d2", GOTO="ZTE_ZeroCD"

SUBSYSTEM=="usb", SYSFS{idProduct}=="0001",
SYSFS{idVendor}=="19d2", GOTO="ZTE_Modem"

LABEL="ZTE_ZeroCD"
RUN+="/sbin/rmmod usb_storage"

LABEL="ZTE_Modem"
RUN+="/usr/bin/usb_modeswitch -W -d 1 -v 0x19d2 -p 0x2000 -V 0x19d2 -P 0x0001 -m 0x04 -M 55534243123456780000000000000600000000000000000000000000000000"
RUN+="/sbin/modprobe usbserial vendor=0x19d2 product=0x0001",
MODE="660", GROUP="uucp"
LABEL="ZTE_End"

Then install usb_modswitch, following instruction per normal from website

I did comgt by comgt -d /dev/ttyUSB0

And voila, either using wvdial or GNOME PPP, both working well but not the USB plug.

So, I am back to use my USB at forget (at this moment) using ZTE in my AAO.

When I browsed more or check the usb_modswitch or similar forum and get better solution I would share.

Thx & bye, AG

Japser, thx for info but could not register to the forum probably because not using australian hosting that I might try it again in future. Let me check on advise to swith with 8 & 9 if possible to work with my ZTE MF620
