reversing a pro duo to usb reader

Postby pvp_lostknight » Mon Dec 31, 2007 11:45 am

what i want to do is take this pro duo to usb reader

and wire the end of the pro duo side to my device (which reads pro duo) and wire the usb end to a usb flash drive. would that work in theory because it is bi-directional?

Of course not. There isn't ANYTHING in common between device-side and host-side implementations of USB. I'm not sure what "pro duo" is, but I suspect it is similarly asymmetrical - that's the way protocols tend to be designed these days.

is there ne device that can do what i want it to do or is there a way i could solder some parts together to make this happen?

What you are describing would require a major development effort. Given that most uses of Pro Duo memory sticks are with portable devices, where the bulk & increased power consumption of an adapter would be extremely undesirable, I'm not too surprised that no such device appears to exist already.

There would certainly be more to it than just "soldering some parts together" - most of the development work would be in programming the FPGA and/or microcontroller needed by the adapter.

Why not just buy a Pro Duo Memory Card and use it in the device?

the device that i have uses pro duo as it's main memory. its also got a usb port for data transfer. it goes into usb-a type so i can plug it into my pc to transfer data to the pro duo that's inside the device. it's also got a usb-b type and a special program on the device (while having a usb cord connected to the pc and a special driver on there) will let me navigate my pc and launch programs designed for the device from my pc. im basically trying to get more out of my device thats all

about the only way would be to use a fpga/clpd and have it programmed with a msp device logiic so it looks and responds like a mps device on one end and a usb mass storage host on the other end to control the usb drive and have logic circuits designed in the middle to translate the data as it passes from one to another.

this is a very simple explanation. honestly the odds of you pulling it off are very slim. it would take someone with a very good understanding of fpga's, usb mass storage protocol, and the msp architecture(which sony is very tight lipped about and you might have to reverse engineer it if you can't find all the specs you need)

I have a feeling this has something to do with the post on hackaday...
http://www.hackaday.com/2008/01/03/psp- ... drive-mod/

IMO, I believe it's a fake. I believe It is entirely possible, but some of the statements are out of wack. A 200GB hdd inside the PSP? No way, well, maybe if it was SSD, but most definately not for anything close to under 100$. Plus, it would have to be gutted and reassembled.

I hope you get the thing to work, but from the looks of the questions here, and the post on hackaday, the two just dont jive (pro duo to usb? yet, you're using a hdd? nah).

this is a different project. and yes it was gutted with major removals of everything that just barely made it work.

This has already been done, actually.

http://www.superufo.com/product_html/PC ... APTOR.html

MicroSD to Memory stick. Easily disassembled and used as a generic SD to MSPRO adapter. Only $5.87.

Sandisk just announced a 12GB MicroSD card at CES.

Standard SD adapter:

CF 4GB Microdrive (designed like above)
http://www.superufo.com/product_html/SO ... _Pack.html

There's other adapters out there if you look -- NeoFlash has made many:

Sold here:

Anyone down to reverse engineer the FPGA code they used to 'emulate' a memory stick?

tried every way and it is not possible because there is no way to get a usb controller on the board. project done. thanks guys!
