Hello Stackoverflowers!
I am currently working with the ATMEL evaluation kit AT91SAM9G20-EK.This kit uses the AT91SAM9G20.
Jan 09, 2007 The Atmel-ICE uses winusb and HID kernel mode drivers which are standard drivers from Microsoft. The Atmel-ICE also needs a user mode driver from Atmel. Being user mode, it has no direct access to the kernel so it can't be a security threat and doesn't need to be signed. Atmel usb cdc After installing the driver, it can be tested by using the SAM-BA application software on the PC, or by using a terminal sub as shown here. As discussed in the previous article, we will use the CDC communications device class module. Once the SAM-BA monitor is programmed, customers can use SAM-BA as a tool to re-program the MPU or MCU, without connecting to the debugger. SAM-BA key features: – Perform in-system programming through JTAG, RS232, or USB interfaces. Atmel's Integrated Development Platform (IDP) allows you to quickly create a microcontroller application by seamlessly and intelligently integrating peripheral drivers, components (displays, flash chips, etc.) and services (file system, USB class drivers, etc.) with Atmel's feature rich IDE and online services.
I am trying to experience USB Device-Port programming and installed ATMELs CDC-USB Device project onto the processor. Putty listens at the DBGU-Com port and everything works well - if you plug in the usb-device cable - the gpio ports are throwing interrupts, the connection has been recognized and even Windows 7 sounds out its typical 'de dem'-sound to acknowledge USB-connection.
If everything went well - the device manager should show an AT91Serial USB-Device USB->Serial Port.
BUT: The ATMEL supplied driver for the recognized AT91Serial USB-Device is not working properly. I asked uncle google for several days, found some sites and referrals and similar drivers who should work, but none of them does.I contacted ATMELs support, but the ticked is still pending.
So i ask you: do you have experience with AT91 USB programming (or similar?) under Windows 7 and a working driver for me? Or a workarround?Pity i didnt have experience in windows driver programming -.-
Thank you for reading and helping!
Regards, Aureon

Here's my solution as i posted it at at91.com:
First:Configure Windows driver signature behaviour:
- click on the windows logo in the left bottom corner
- type in the field gpedit.msc (or in cmd-console)
- it will open the editor for group-rules
- go to user configuration-> administrative templates
- select system-> driver installation
- select code signature for device drivers
- select the 'active'-radio button and choose 'ignore' from the dropdown menu below.
This will set windows to continue driver installation if its unsigned.

Second: Get the latest driver:
- get the latest Sam-Ba distribution and install it
- put the inf-file located in 'Atmelsam-ba_2.12drv' ('atm6124_cdc.inf') into 'Windowsinf'
Third: Do manual installation:
- uninstall the current decive at the device manager (should be 'AT91USBSerial' with a '?'-icon)
- Unplug the device.
- Plug in the device again.
- Windows should open a driver installation window and either notify you that the driver has been installed or that it failed again.
- open the device manager
- rightlick at 'AT91USBSerial' (with the '?'-icon) and choose update drivers.
- select 'Search computer for drivers'.
- select the list option -> Search for 'Ports(COM & LPT)' -> select ATMEL Corp. and select 'AT91 USB to Serial Converter' and click continue.A red warning window should appear. (You serious to install??)
- Select the option 'Install unsigned driver'.
TADAAAAAAAAA!There it goes.Finally! It took me so much time to get it to work so i hope that i could help somebody who has this problem in the future.The driver works well and the Evaluationboard is shown as a new COMP-Port in the device-list.

Very useful, but for windows XP select direct system -> code signature for device drivers [enabled] -> [ignore] also is needed to go in control panel -> system -> hardware -> driver signatures button, where select again ignore. after this update the driver and it work
