Hey guys!

i've put an executable Linux script on my sd card. now, i would like to download that file when the camera is connected to the pc. Problem is that my camera does not show files that are not standard.. (jpg, cr2, foldrs named 100Canon, etc..) Through the ptp protocol I only see what the camera wants to show.. also tried renaming the executable to .jpg but no luck.

any idea on how i can make that file show up so i can download it from my camera without having to take the sd card out?

thanks!

You don't say, Micro or Standard SD cards? Here's one for the standard, http://www.ebay.com/itm/USB-SD-MEMORY-CARD-READER-MMC-RS-MMC-TF-2GB-4GB-blue-color-/111403728180?pt=US_Memory_Card_Readers_Adapters&hash=item19f02dfd34

Just an example, 78 cents free shipping to US is pretty cheap? Might vary depending on your location.

Buy a few, one for the laptop, one for the desk, one for the next time it stops working. I bought a dozen last batch and gave most of them away to friends.  They do go bad sometimes. I think when I was transferring large videos I burned one up.

Or for Micro SD it's just as easy. Search eBay BIN listings. "Micro SD Reader" If you are in a rush, go to a store and get one. Again since I don't know where you are, it's kind of difficult? One of the problems with the many anonymous users here.

(I'm not an expert) 

i do have a sd card reader, but thats not what i need.. i need to be able to download that file while the card is inside the camera.. thats the Whole point of this question..

If you explain why you need to do that I can probably help you with what you are trying to do. Maybe link to the instructions which you are following.

What are you trying to achieve ?

ETA: have you tried using MSC instead of PTP ?

I have a router running openwrt and need to execute a huge file. (Huge in prop. To the internal storage). I need this router running linux to downlaod the file if it fonds it on the camera and run it

I do not believe that you are going to be able to do this using ptp. Some cameras (eg Nikon) allow you to configure the settings such that the camera is seen as just another drive.

Depending on what it is you are trying to achieve, I think that you might be better addressing this question to stackexchange.

None of my business and I hope you don't mind me asking - but why are you trying to do this ?

i am working on my wireless tethered shooting rig, and the executable is too big to be placed in the router's memory. So i have to download teh file to the router each time. To avoid having to connect a usb stick first that downloads the file to the router and then connect the camera i wanted to download it directly from the camera to ther router.

But currently i am aproaching another solution and i am building my own openwrt build. i have just another minor problem with the DHCP on the access point settings and then i am up and running... will post the instructable (the updated one) as soon as its finished.

here is the topic that explains a bit more with a link to the current instructable:

http://www.microstockgroup.com/general-photography-discussion/wireless-tethered-shooting-with-any-dslr-camera-for-cheap/

but as said i am working on it to make it a lot better! it will be like: buy the router, hook it up, flash a intermediate firmware, flash my custom firmware (up to here its about 5 minutes Worth of time without counting the ordering and delivering time of the package... ) reboot, and you have a running access point to connect your laptop to! you only need the host on the computer and its ready to run!

as soon as this version works ill post a better instructable!

here is the video of how it works from when you fire it up to when you see the picture on the pc!
