Is it possible to get the source code of the atm6124.sys driver (PC BasicUSB Application)? I am getting the "Blue Screen of Death" when running the Windows API ReadFile as a thread. Yes, I know I would have to compile the driver sources using Windows DDK.

Try sending this question to:

"at91support [nospam] at [nospam] atmel.com".

Let me know if they send it to you. I'd really love to see this myself!

I do not need it anymore.
Finally, I had to learn how to write kernel-mode drivers and write my own USB driver. The driver works very well.
No much help from Atmel. Too bad since the company I work for buys a great number of Atmel products. The problem with Atmel is that although it has excellent products, the marketing and customer support is lousy.

Did you base your driver on one of the demo apps in the DDK? Were any special tweaks needed to talk to the Atmel chip?

Please share any hints you may have to make this easier. I am new to USB coding and I'd like to get smart on it, I have VC++ and the DDK.

Hello,

I have exactly the same problem. I am using the BasicUSB driver that came with the ARM 7 evaluation board. The USB firmware in the ARM 7 contains a custom device class with 1 interface and 2 interrupt end-points. I have made the necessary changes to the atm6124.inf like the VID, PID, names etc, but using the same atm6124.sys. After I plug my device in, it enumerates properly and it asks for the driver. The moment I point it to the inf and sys files, I get the blue screen of death.
Questions:
1. Is it at all possible to use the driver that came with the board with my own USB application on the ARM 7?
2. If yes, any idea how to debug the blue screen of death. One thing thats for sure is that the system crashed while loading the driver.

Any help will be appreciated.
Thanks in advance.

I don't have any answers for you, but I'd like to know which version of Windows you are using, and whether your PC came with USB 1.1 or 2.0 ports?

Windows drivers for WinXP and 2003 are not compatible with Windows 98 and 2000. I think the Atmel driver was built for XP. I'm not sure if they also include a separate version for Win98?

I have Windows 2000 SP4 and my PC came with USB 1.1. The Atmel driver for the BasicUSB works fine with the firmware that came with this application, but if I change the firmware on the ARM7 with my own customized USB device, I get the blue screen of death when the driver is being loaded.
So, its doubtful that it has anything to do with the OS.
Thanks.

I need this driver!

I have the same Problem .
It seems that ReadFile and WriteFile can not run in the same time .When ReadFile is in progess ,the WriteFile should wait until the ReadFile is finished.So ,The Synchronization should be established between the Read thread and the Write thread.
