How to interface 3G usb modem to any ARM (Android / linux ported) Board.  Hi I am now going to provide quick steps to interface the 3G usb modem to linux/ Android SBC which i have tried during my try which is successful one . More and more USB devices when plugged in for the first time they act like a flash storage and start installing the driver from there. After installation (and on every consecutive plugging) the driver switches the mode internally, the storage device vanishes (in most cases), and a new device (like an USB modem) shows up.       Few modems (Huawie) most of time they do not need to switch from mass storage to usb modem mode.

When i was in 3rd year this idea got stuck into my mind as we had to exchange some soft copies of important documents and the PC's we were having at my place (In my Engg. Collage) were USB disabled PC's and we were helpless at that time. While talking with my friend i just said to him, "transferring data should be so easy so that if we connect two USB Flash drives (Pen drives) directly to each other then they must be able to transfer the data." But by only using Flash drives it was not possible because they are not intended for that purpose. To do so we must have certain kind of interface. Hence i decided to give such an interface to make this happen. And finally i came with this device. This is ve...

EFY had asked for suggestions on various development boards those are popular now a days in Hobbyist. I had been quoted into the same with my suggestion. Look at the other suggestions too who have already worked on these boards. Have a look at my interview on EEWeb community.  click here
