Oh i almost forgot....here is what the company that makes the thing says...
Dear customer,
Thank you for your inquiry.
So far, we have no plan to provide Linux driver by ourselves and support it.
But actually, the Linux driver of the chip implemented in the CFU1U is available on Cypress Web site,
http://www.cypress.com.
The chip in the CFU1U is Cypress SL811HS.
http://www.cypress.com/products/datasheet....partnum=SL811HSIf the code is added PCMCIA function, I think you can use the CFU1U on Linux.
Here is I/O register map of the CFU1U.
I/O base address + 0:SL811 address
I/O base address + 1:SL811 register
I/O base address + 2:SL811 register
I/O base address + 3:SL811 register
I/O base address + 4-7:not used
These are the only information that we can provide.
One of our customer seems to have made the driver as follows.
Please take a look at:
