Bob,

My initial ideal was to access the USB using a pic device.

I found a the product "Au9381 - USB Flash Disk Controller" from
www.alcormicro.com that can be the solution for it.

Regards,

Vitor

Assunto: Re: USB Memory Key


I'm doing a design in which I am using a Cypress SL811HS as an embedded
host driven by an '877, to talk to a USB Memkey.

Its an awesome task. To make the job easier to troubleshoot, I have
committed a 166Mhz DOS system to a Pascal Host, by debugging all the
routines in Turbo Pascal. I am driving the SL811HS via the bidirectional
LPT1 port. The reason I am doing it this way is that it eliminates all the
PCI stuff, and I am interfacing it to the 877 Parallel port, which is
almost identical in action.

I am attempting to adapt USB4DOS, a fine USB DOS driver for SOME host chips
(by Dieter Pawelchek). Once I get this running, then I can concentrate on
how the MEMKEY  is organized. My guess is that internally, its just memory
organised like a harddisk, and I can locate the critical record areas. But
I don't actually have ANY info on how they are internally organized.

I have another populated SL811HS/USB/Parallel port breadboard to anyone
that would like to assist / be assisted in this. Just email me privately.
