I'm struggling to create a Debian 7 netinstall live usb key which can boot with efi.
I can't find documentation or tutorials about this manipulation.
Debian 7 is efi ready ootb.
The mistake I made is that my usb key was formatted in NTFS rather than FAT32.

I have done this when running Debian using gpsd. But when running Windows IoT preview...what is a way to get the NMEA sentences off an attached GPS (on the USB port). Is that kind of support around yet?
Currently this support is not yet available but it is being actively developed. Furthermore the Geolocator API is broken. Unfortunately I don't have an ETA for this but its coming.

I need to communicate with some custom hardware that will use either a FTDI or Silicon Labs usb to serial driver.
I found a couple examples but they are older and was hoping for a more up to date example. Plus, I have been confused by the new AppleUSBFTDI kernel driver in how that works with the IOKit and other chips like the Silicon Labs part. It would be nice to have one program that doesn’t care which driver is used.
I have already looked at this example:
FTDI Communication with USB device - Objective C
The nature of these drivers and devices is that they are supposed to function as a standard serial port virtually over USB. So in terms of access it should be no different than accessing a standard RS232 COM port.
I would suggest reading the Serial Programming Guide for POSIX Operating Systems. I'm not sure what older examples you're seeing but serial access itself is many years old, but the idea behind communicating to the serial device is the same in the case of these USB to serial bridge devices.
For information on some Objective-C frameworks, take a look at this Stack Overflow post.
Finally, here is an article directly from the Apple documentation, Working With a Serial Device, and you'll see it also references the POSIX style API.
You should simply need to install the driver associated with your device and plug it in for this to work. In terms of the Silicon Labs CP210x device just download and install the OSX driver. Then plug in your device. This is where the one difference may show up, the name of the tty device on the system (it will show up in the /dev directory). In the case of the CP210x it will show up and be accessible as tty.SLAB_USBtoUART or cu.SLAB_USBtoUART. This will be the name of the device you should open, then use and API from above to start your communication.
So, I need to read data coming in from the USB port. Normally I do this with Realterm when I am on a Windows computer. But now I am on a linux computer and would like to do the same thing. What is a good replacement?
Thanks
Use libusb - see http://www.libusb.org/
It comes with lots of functions/source/samples for USB and allows reading/writing etc.
It is licensed under LGPL 2.1
realterm is a windows terminal emulator. Here is the SuperUser thread that got closed on the same subject.
I'm new to CE programming and I have a Marvel device PXA270 with Windows CE 5.0 installed. The device has one usb port.
I wonder if there's ANYTHING I can try to connect a 3G-HDSPA usb stick to it. When plugged it only recognises its folders as a pendrive would do, but no Internet.
Thx.
Forget it. To make it work you need OS support for it or a dedicated infrastructure that the cellular modem should provide for Windows CE 5.
To have cellular support you need Cellcore included in the OS and Windows CE 5 does not support it.
What you can do is start develop your own infrastructure for the device, but it will take you several months of work and that is if you have the Cellcore code from Windows CE 6 as a reference.
The short answer is that you must have a Windows CE driver for the device. Obviously it's a composite device that enumerates as a storage device and also whatever the radio is. Windows CE understands the storage device part and therefore loads up the driver for that. It has no idea what the radio is.
You would have to either get a driver from the OEM (they probably don't have one, though it's always worth checking) or write your own (you probably don't have enough info on the radio chipset to be able to do that).
I need an Open Source solution & tutorial for creating mobile streaming server that can stream video on 3gp (3gpp) format, i have tried using Helix DNA Server, but it's free version only allow real media not 3gp.
I have heard about DSS (Darwin Streaming Server) but i can't found any Windows binaries (compiled exe) for that, and Catra Streaming server package only confused me more since i can't found any file required for Catra (setting, etc are missing on their package).
PS: Actually i need some sort of guide for setting DSS or Catra on Windows (especially Server 2003)
You may want to try VLC http://www.videolan.org/vlc/
I can't vouch for the streaming server, but the player works well, and 3gp is supported.
But this isn't a programming question.
DSS Windows binaries are here:
http://dss.macosforge.org/post/previous-releases/
If you're target mobile devices support flash you can stream 3gp from Red5. If they don't support flash, but they do allow HTML5 you could still use Red5 or pretty much any Java EE container server.
