USB connection feedback on my GUI

Feyd-Rautha · 12-29-2005, 09:20 AM

Hello!

The application I'm working on supports the use of a UMTS phone connected via USB. Everything OK with that, the only thing I need is a fast feedback on my GUI (it's made of web pages) when the user connects the USB cable.
The only solution that came to my noobish mind

is to use javascript/php and go check /proc/bus/usb/devices every 0.5 seconds but it doesn't sound very smart

Please can anyone give me some hints??

It depends on the scope of the app, where will it be running? Is it going to be accessible remotely or only on the computer with the phone connected? If it's the later then go Javascript or if you feel like forcing a Gecko-engine browser on your user then XUL.

Thanks for your help!

The interface will be available remotely for all the machines in the LAN where the computer is going to be installed...

Well in that case PHP should be fine, you can use the output buffering (ob_*) functions to do some pretty neat stuff that would look like the page was updating live. Example, put the PHP script into a while (1) loop and then just draw <div> elements over each other with updated status text.

PHP is a pretty cool language, look into chat scripts written in PHP for example on how to make a page appear to be updated on-the-fly
