Then you are lucky, because the source code of the Linux Kernel is licensed under the GPLv2 and this constrains the seller to make the modified source code, if he actually bothered to modify anything, and he probably did, available to the customers (and not necessarily to the public) free of charge. | + | * Most probably it's a kind of outdated GNU/Linux Kernel with FOSS drivers or with binary only drivers or both.

| Now maybe the drivers for the components have already been integrated into mainline kernel, which means that a newer kernel should work on this device out of the box. If not, you could continue to use the one, from the manufacturer.

Please do not bother developers or potential developers to write code for this. Present the information you gathered, if it is interesting enough, somebody is going to do that ;-) Now to write code, the developer needs only some bread and water and a simple text editor, but to test this code, he's going to need the hardware itself. You could donate or maybe just lend the hardware. | + | or in the **mainline kernel**. If not, then consider adding a new device or a complete new platform to develop software for.
