enter image description here cant access the directories in media file system on my mobile via my Ubuntu 14.04
can anyone help me?

Restart the ubuntu system and your phone. Try it again.
Which connection mode your phone is in? MTP or USB mass storage?
Check your cable. And are you able to connect and use other USB devices on this system? Are you able to use this phone to do transfers on other computer?

Can't log in to embedded Linux Buildroot

I'm looking to install Linux onto an Intel Galileo Gen 2 utilizing this and this via installing onto an SD card.
I believe I have successfully done this, as during the boot sequence I am able to select Linux to boot from, however as soon as it starts booting from Linux, I am unable to interact with the Galileo anymore by say typing in my username and password when it comes time to login.
I'm unsure if my peripheral setup is wrong, if I need to install some more drivers to support I/O or something else.
I am viewing the logs from the Galileo via an FTDI cable and currently have a keyboard plugged directly into the Galileo.
Log data
When I boot the Galileo, this is what is logged.
Interestingly, the
flashing cursor stops flashing and is just steady when I get to the
login screen, as if the device is sort of frozen
However if I then
say connect a keyboard, it recognizes it and outputs this log data.
Solved! Turns out it was a faulty FTDI cable!

virtual machine Audio Device Rename

I am trying to rename my audio device name. but it doesn't do anything when I rename it. it just simply close the setting. My setting for RDP is Local Resource-->play on this computer.
Its not possible to rename the audio device name on the VM as you are using remote audio driver from Microsoft to output the sound to your local machine . The driver name is bydefault remote audio.

USB drive file access history

I recently forgot my USB drive at work and a collegue found it. I got the drive after 4 days. I have a feeling my colleague accesed or copied my personal files.
How can I find out?
You have no means to know whether he copied the files or not,as such auditing can be enforced only with particular domain policies on machines where users have no privileges.
For example, you coworker could have unplugged the USB stick, and plug it on his personal computer. It worse, if he had Linux, just mounted the USB stick in read only to prevent timestamp changes.
Note that on windows you can do the same. To prevent thefts, you should encrypt the USB stick.

Windows CE HP iPAQ - USB Stick

Hi all Windows CE developer,
is there an option that a Windows CE device (HP iPAQ) acts as a "normal" USB-drive if it will connected to PC. In this case I have an linux (embedded) device and I have to copy some files from iPAQ every few seconds.
I can not change or recompile any CE Firmware from this devices. The best would be a program to get the USB-drive possibility.
I tryed an CE-ftp server but it did not work because of the "RNDIS" stuff - TCP/IP is missing.
The ActiveSync did not work with linux. I only could get an usb-ethernet connection with RNDIS but without the communication library it makes no sense. "Synce" did not work as well some derivates.
thanks

FTDI chip detection issue

I'm trying to do some transactions over serial ftdi interface to an ARM based board. On windows i'm able to detect it but when from virtualbox i'm unable to detect the same.
When i connect the same board to a linux sever box, it gets detected and gives me the port /dev/ttyuSB0. Any idea why Virtualbox does not detect?
By default, your VMs in VirtualBox can't see any of your 'real' hardware. You can "move" a USB device from the host to the guest. (Appears as a disconnect from the host, then a connect to the guest), but it's an odd two-step process:
When the VM isn't running, create a USB "filter" on your device.
Then, when it's running, sometimes it grabs it, and sometimes you must click the USB icon (at the bottom of your running VM window, next to your disk/CD/mouse indicators).
Make sure you have a recent version of VirtualBox. I think before 4.x, the USB support was not included in the free version. But I can confirm it works in 4.1.
