Re: Problem with an M2 Card in a USB Card Reader

I know my computer picks up the card as in the "device notifier settings" automount section it registers then reregisters the device repeatedly but it obviously doesn't mount it.

??

When you plug the card in, something like this happens ?:

1) The device notifier pops up
2) You click the "Open with File Manager"
3) The file manager doesn't show up.

If so, open a konsole window and type the dmesg command (https://help.ubuntu.com/community/LinuxLogFiles).

Are there any error messages ?
With the error messages you could do net searches.

Re: Problem with an M2 Card in a USB Card Reader

No device notifier doesn't pop up.
After it not popping up I opened it manually and went onto its settings.
I saw in the automount section of the settings that it was connecting repeatedly to the card but nothing showed up on the actual widget or in Dolphin.

Re: Problem with an M2 Card in a USB Card Reader

An example - How it is working at here

1) Plug in the empty usb memory card reader.

The dmesg is telling:

Code:

:~$ dmesg

[ 5604.076079] usb 1-1: new high speed USB device number 2 using ehci_hcd
[ 5604.876308] usbcore: registered new interface driver uas

[ 5605.912503] sd 4:0:0:0: [sde] Attached SCSI removable disk

and the lsusb is telling:

Code:

:~$ lsusb

Bus 001 Device 002: ID 058f:6366 Alcor Micro Corp. Multi Flash Reader

2) Plug in a memory card

The dmesg is telling:

Code:

:~$ dmesg

[ 5888.515380] sd 4:0:0:0: [sde] 7744512 512-byte logical blocks: (3.96 GB/3.69 GiB)
[ 5888.520867] sd 4:0:0:0: [sde] No Caching mode page present
[ 5888.520874] sd 4:0:0:0: [sde] Assuming drive cache: write through
[ 5888.523522] sd 4:0:0:0: [sde] No Caching mode page present
[ 5888.523531] sd 4:0:0:0: [sde] Assuming drive cache: write through
[ 5888.527990] sde: sde1

The memory card is /dev/sde1. The blkid is telling:

Code:

:~$ sudo blkid

/dev/sde1: LABEL="CELLMEMCARD" UUID="3362-3364" TYPE="vfat"

It is a fat32 format with the label CELLMEMCARD.

There is a device notifier.

3a) Mounting with the device notier, clicking the "Open with File Manager".

The memory card is mounted: /media/CELLMEMCARD/

3b) or Manual mount

Making a mount point:

Code:

sudo mkdir /media/external

Mounting:

Code:

sudo mount -t vfat /dev/sde1 /media/external

The memory card should be mounted to the /media/external or there should be error messages.

NAME
    lsusb - list USB devices

SYNOPSIS
    lsusb [ options ]

DESCRIPTION
    lsusb is a utility for displaying information about USB buses in the system and the devices connected
    to them.

How / What is happening at there ?

The input (what you are doing) with the output (dmesg,lsusb...) will make the helping a bit easier.

Re: Problem with an M2 Card in a USB Card Reader

With just the empty reader plugged in;

The dmesg:

Code:

dmesg
[ 6208.248045] usb 1-1: new high speed USB device number 2 using ehci_hcd

The lsusb:

Code:

lsusb

Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 3207:0300

Then after inserting the memory card into the reader;

The dmesg:

Code:

dmesg

[ 6945.764118] sd 7:0:0:0: [sdb] Assuming drive cache: write through
[ 6945.765000] sdb: sdb1

I have shortened this. The errors filled the whole terminal. Terminal would not scroll as far up as the actual command.

The blkid:

Code:

sudo blkid
/dev/sda1: UUID="ec3f7ae1-4c20-4a78-8da2-8da7b45d526b" TYPE="ext4" 
/dev/sda5: UUID="4381983f-4b22-4b9e-a40f-3d05e0d373f2" TYPE="swap"

Attempting to mount;

These commands did nothing:

Code:

sudo mkdir /media/external
sudo mount -t ext4 /dev/sda1 /media/external
