AT91USBSerial and Windows 7 - working driver needed

Wed Sep 05, 2012 1:00 pm

Hello!

Like in the title above i need a working driver for the AT91USBSerial USB CDC Driverproject from ATMEL for the AT91SAM9G20.

I found 10 or more different drivers on the internet and for each one it has been said that the driver will work 100%.
I even used the driver from ATMEL but it wont help.
The system recognizes the AT91Serial Device, but wont accept the driver.

Can anyone help me please getting the right driver?

I have to use this for serial I/O (internal) and need to get experience in USB Port programming to use a wireless stick later on the USB Host port.

Regards,
Haidosu

Do you have Win7 configured to reject unsigned drivers?

The drivers supplies with the most current version of SAM-BA should be viable with Win7 32 and 64-bit.

Thanks for your reply!

I have configured WIN7 with this settings:
Code signature active and continue driver installation when unsigned driver was found. [ignore].

Mhm.. looks like Sam-Ba hasnt provided me with a driver.. i'll reinstall it.

I'll finally got it!

So here's my solution for everyone who has problems with the USB-driver in the future:

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
- goto 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 newest Sam-Ba distribution and install it.
Then put the inf-file located in "Atmel\sam-ba_2.12\drv" ("atm6124_cdc.inf") into "Windows\inf".

Third:
Deinstall the current decive at the device manager (should be "AT91USBSerial" with a '?'-icon). Unplug the device.
Plug in the device again.
Then Windows should open a driver installation window and either notify you that the driver has been installed or that it failed again.
Go to the device manager and rightlick at "AT91USBSerial" (with the '?'-icon) and choose update drivers.
Select "Search computer for drivers".
Select the list option -> Search for ATMEL Corp. and select "AT91 USB to Serial Converter" and click continue.
A red warning window should appear.
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.

Anyway: thank you for the help.
(And to be honest: forget the ATMEL support, because they said that there is no solution for my problem.)

Regards,
Haidosu
