USB stick failed to connect

Asked by Luis M.Jacinto on 2013-09-08

Ubuntu 12.04 precise
USB Stick SanDisk Cruzer Blade

Stick failed to connect to any off two computer USB connections
I have an keyboard with other two connections and from this it connects with name
“/media/5E10F5A110F7FF7”.
Any other sticks connect to both connection with name “media/PENDRIVE”
How to force SanDisk to connect from the computer USB connections?

Hello,

the name is not a problem. The mount-point is created depends on how the Linux kernel recognizes the USB-stick. So either PENDRIVE or 5E10F5A110F7FF7 this is not a problem.

If you want to force to connect the USB-stick under a specific mount-point, then you should do this manually.
First create the mount-point

Open a terminal (CTRL+ALT+T) and execute

    sudo mkdir /media/cruzer

Then connect the USB and if it's mounted automatically, umount it with this command

    sudo umount /media/5E10F5A110F7FF7

and then mount it at your mount-point

    sudo mount /dev/sdb1 /media/cruzer

Now , the /dev/sdb1 is just a paradigm. You must find the correct /dev/sd?? with

    sudo fdisk -l

there you will see what is the exact name.

All above is for mount the USB where you want.

If you have an actual problem and you cannot access your files in that USB, then connect it to the port and give here the results of

    dmesg | tail -n 30

The errorcode -110 means: "power exceeded". You already have many power consuming devices on the bus and the system can not give the required power to the device. This usually happens on non-powered USB hub only. If it happens on the connectors directly on the PC there might be something wrong with the USB equipment in it. If you do not have enough ports you should use an active (powered) usb hub. The power adapter should deliver at least 0.5×(number of ports) A, e.g. 2.5 A for a 5 port hub.

For further diagnosis I need the full output of this command:
lsusb -v 2> /dev/null| egrep "(Power)|(Bus)"; lsusb -t

There are two problems:

1. the device reports to need 500mA, that is the maximum USB can supply. There is aready an device requestion 100mA,
2. It looks like you have only one USB 2.0 port, on which you have a hub, that should be the keyboard with a built-in passive USB hub.

The best option would be to use a powered USB 2.0 hub on the port where the keyboard is connected and connect the keyboard to the hub. An alternative would be to to connect the hub to the keyboard. The connect the stick to the hub.

Connecting the stick to an USB 1.0 port is not a good idea, they are very slow.

This is by the way not an OS limitation but a limitation of your hardware.

Can you help with this problem?
