Gemalto readers + .NET : freeze on laptops with American Megatrends EFI / UEFI firmware | Telit Cinterion IoT Developer Community

December 18, 2015 - 2:26pm, 2988 views


I faced an issue on several laptops  that have an American Megatrends EFI firmware. When I connect a K30 smardcard reader or PC Twin reader with a .NET card before to start the laptop, the firmware is frozen. When I remove the K30  USB stick, the boot is OK.

I faced the problem on different devices and the common point ids the EFI :

- Surface Pro 2 with American MegaTrends 2.15.1226

- Surface Pro 3 with American MegaTrends 2.16.1243

- ASUS Pro BU 401 L with American Megatrends 2.15.1236

- Clevo laptop with American Megatrends 2.17.1246

Other test :

K30 reader WITHOUT .Net card : OK, no freeze

PC Twin reader with .Net Card inserted : KO, freeze

---> this is really the combination Reader + .Net card inserted that is KO

I don't know if there is a workaround, but it's blocking at each restart our laptops.

Is anybody facing the same issue ?

Best regards
