Seems easy to make something similar to the Deneb PCB (warning big image!). It's a Xilinx XC2S50 speedgrade 5C. In essence the simplest the FPGA Xilinx has, it may even be out of manufacturing.
The large chip at the top-right is unreadable. But it's likely an USB interface chip. The smaller chip to the left-middle is however a question.

In essence DENEB seems to be a simple FPGA, USB interface and support circuitry like boot-EEPROM and power. So it's not that hard to make a replacement. Driver compatibility may be an issue though.

Creating a cable to upgrade the on-board EEPROM should be that hard either.

Advertazing would definitly get your attention ;)

Maybe users could cooperate to write their own USB stack which could be used with Michaels hardware?

Also, why does Chris Hodges seem to have problems with hardware developers?


Maybe it's Michael that have a problem with software developers?

You simple don't know what's up. Better leave it at that until we know. The only thing we know now is that we don't know the complete picture.

Anyway!

If only a few drivers is missing, then i should be easy to fix a working solution ?

Or hardware companies have a business culture that clash with software development mindset.

I think the focus should rather be on fixing a solution than anything else.

That's not going to happen if there's custom hardware though; can't get a datasheet on an FPGA program, so can't write a driver.
The only hope is if the custom bit is transparent to the controller chip. If it is then I think I smell a bounty....


The datasheet on the USB interface chip should be retrievable. If one additionally traces the PCB one could create a new FPGA binary for the existing hardware. The other method is to debug the existing driver and use that as a reference to get the API, and build a new driver from that.
Neither is rocket science, it's just hard and takes some time.

These things will happen over and again as long as people let them self depend on closed software or hardware.

If you can sell the plain hardware and provide the hardware API documentation as seen from a programmers view. And there exist free USB-stacks. Then the current USB option deficit can be solved?

If I would make an Zorro USB solution then I would stick to something that can be achieved with reliability, like plain Zorro-II. The rest can be dealt with a later time.

The Cloud is perfect when you want to invite state-, corporate-, crime and other spies into your data. Tracking and manipulation of your data etc.. Access dependent on your wallet and the employee turnover etc.

Someone that may need this data may come around when the original producer is no longer around.

What problem are you refering to ?
