Is it possible to doing what any script / code local_site.ru.dev - access usb devices (flash drive, SD card and other drives) connected to client computers? Accordingly, pressing or not pressing any buttons on it local_site.ru.dev

Using any web programming technology, you can make it happen.

I would be very grateful for the detailed response.
You're requirement is not so clear, but in order to access a physical drives on client machine, You may need technologies like; Silverlight (Moonlight - on Linux), or Adobe Air, etc.
Or, You also can use ActiveX which is a traditional way do so what such a thing you need.
However, if your requirement to develop an application where to deploy-once and use from many clients, then why don't you try Out-Of-Browser Silverlight + Auto Update.

I'm currently doing a test UWP app, the goal would be to put this on a Raspberry PI with Win 10 IOT ont it.
I've not much content, the application just display all the zodiac signs, and when one signed is clicked, it displays the current sign information. This will be display on a monitor here. So I would like to be able to navigate between sign, with a remote by example(but I'm open to any other proposal).
What would be the more adequate to navigate on the application(knowing that I don't need to enter anything, that it's not a touch screen but a simple monitor).
Thank you
You could use the GPIO port on the Raspberry Pi to connect the device with any of external controllers of your choice. Wired buttons would be pretty simple, and for a remote your could use an infrared receiver. The GPIO allows you to interact with pretty much anything electronic so the possibilities are pretty much endless.
For interacting with the GPIO port you need to add a reference to the "Windows IoT Extension SDK" to your universal windows app project.
The samples repository has code examples on how to interact with the GPIO port, and many of them are explained with tutorials.
I am trying to connect my POS Terminal(WinCE Secure Multi-Application Operating System,200 MHz ARM 920T 32 bit CPU) to my windows 7 PC. The issue is i am getting a device driver software issue and the device is not been recognized. I didn't got any installation CD or software with the product.I couldn't find a suitable driver for the same in the web and would need to install the CAB files through WMDC into the device so that i can automate the product testing. Can someone please advice in fixing this driver issue and direct me on how to establish the connection. Any help is highly appreciated.
Thanks,
John
This can be a complex task. First, the connection type (serial, USB, Ethernet, other) is important. I'm going to assume USB, as that feels like what you're probably talking about (you should edit and clarify though).
For USB to work, you need drivers on both ends - the device and the PC - and they need to cooperate. For Windows CE devices and USB, the common way (though not only option) is to use ActiveSync. There is an out-of-the-box client application driver for Windows CE (repllog.exe) - though it requires the OEM actually plumbs it through to the transport driver. For the desktop (Vista and later) you would use Windows Mobile Device Center (WMDC).
You might simply be able to install WMDC and you're off and running, but it's always possible that the OEM disabled that, since you might not want someone to connect a PC to a POS system and subvert the normal operation. Have you asked the device OEM?
I am trying to find a clever way to keep a BLE app active in the background on iOS 6, without breaking any of Apple's rules. I plan to use the phone as a peripheral device and another BLE circuit as the central. My app will automatically be opened when a user arrives to a building using geofencing. After that the iPhone will connect to the first BLE central device it sees (the device will be in its white list). The user will then be able to move throughout the building switching to different BLE "nodes".
My question is: What do I need to do in the background when a user is stationary at their desk so that the app does not get suspended due to memory resources?
My idea is based on this solution for a separate problem: There could potentially (not regularly) be 10-50 users in an area with only a few BLE "nodes" and I read at bluetooth.org that I could setup a dynamic connection system, basically rotating connections through all the users.
My idea is to setup a similar dynamic system where the central device (not the iPhone) disconnects the device on regular intervals (30-40 minutes) and then the iPhone will reconnect.
Is this something that some feasible? Is this against the iOS development guidelines? I was unable to find anything explicit about this. I have also asked on the iOS developer forum, but unfortunately it is not as popular as this site.
Thanks in advance!

I'm trying to access serial port through web browser.
The reason is for downloading firmware to a device that is connected to the same machine that is running the browser (via USB to rs-232).
I'v searched around and have seen that this is doable via Silverlight, but this is Windows only centric since it requires COM support, while my main operating system is Linux, then Windows and then Mac.
I know it's easy to develop JavaFX / QT / Mono / AIR cross platform applications, but those require installing a huge runtime binaries and only then run the application.
I'm trying to keep it really simple, plug your device, visit a web site and it will auto install your application.
Do you guys think it's possible?
Thanks.

Since Java is cross platform, this would be the only thing required to get the serial support you need in browser.
(not exactly a security nightmare as #"awm" proposed) You could implement a websocket on the localhost, expose a port that is rarely used and call that websocket to open the serial port and feed data to the device to upgrade the firmware.
I am writing a windows application (written entirely in C++) which reads files from a storage card on a mobile phone running Windows Mobile. The tough part is, I don't know how to make my application detect the event that a user has connected the mobile phone to the USB of laptop. I did some reading on MSDN and have written a small code using RegisterDeviceNotification, which detects whenever a USB disk is attached/removed from the laptop. However, I am unable to tweak this to make it work for phone type devices. Please help me out through any links/tutroials which explains this(preferrably C++, as I don't know .NET or C#).
Thanks

According to this article you can use RegisterDeviceNotification to get notifications when activesync detects a device has been plugged/unplugged. (See option 3 at the end of the article)
It may just be a matter of setting up the correct notification filter.
Windows Mobile devices use RNDIS, a network interface protocol behind the scenes. Hence, the RegisterDeviceNotification method still works, but you're looking for a DEV_BROADCAST_DEVICEINTERFACE, not DEV_BROADCAST_VOLUME. (i.e. dbch_devicetype==DBT_DEVTYP_DEVICEINTERFACE)
You can use RAPI or RAPI2 to detect when a Windows Mobile device connects to a PC via Active Sync or Windows Mobile Device Center. RAPI can also be used to read the files on the storage card and much more.
RAPI is simpler to program because it is a C based API. RAPI2 has more functionality than RAPI, but is an object oriented COM API. If your needs are simple and you only care about one device/connection at a time then RAPI is good enough. There are two RAPI functions used to detect connections: CeRapiInit (blocking), and CeRapiInitEx (signals an event upon connection).
