USB writefile/readfile to WIN7-64

[Elliott]

 
Hi All,

For about two years to communicate through my usb adapter (AT91SAM7X256) with SITEMA W98-WIN2000-XP without problems
Today with a quad-core machine that has Win7-64 after a few falls communication
WriteFile call returns 0 and the whole plant.
I think the problem is the card because when I reset the whole block.
To all of you not 'ever had a similar problem

Sorry fro my English

Thank-You

32-bit applications sometimes need some mods to be compatible with 64 bits. Hard to be more specific without more info about how you're accessing the chip (what USB class or driver, what programming language, etc.)

Hi

Today I dusted the AT91SAM7S-EK evaluation board, and I uploaded the file Keil USB HID
I took the following zip file USBHIDIO2 for VB6 and after settling the PID and VID I launched the communication
but in this case after xxx telex crashes
I need help, in the tests with the same PC this morning I saw that everything worked, but tonight I can not
go beyond the 10 consecutive telex.
Got the impression that the speed 'of your PC to block the card.
