Hi,

when I try to connect the USB armory Mk II to a Windows 10 computer (not a virtual machine), the operating system does not recognize the device.

It does not appear in the device manager as an RNDIS device as you described.

It appears as a serial USB device (COM6).

Is there a hardware problem?

Hello Karhl,

are you booting successfully our Debian image on the USB armory from a microSD card (e.g. is the white LED blinking) ?

If the device is detected as COM* interface it usually means it is being detected in Serial Download Protocol mode (see https://github.com/f-secure-foundry/usbarmory/wiki/Boot-Modes-(Mk-II) ), which means that it is not currently booting any OS.

Hi,

I am booting from the Debian image on the USB armory from a microSD card. The white LED is blinking.

The switch was originally in the position eMMC. If I slide the switch to the position microSD it shows me the same error pattern. It appears as a serial USB device (COM6).  

kind regards

Hi Karhl,

can show the command used to flash the microSD with the Debian image?

Thanks
Andrej

Hi, 
I use it with a USB-C to USB-A adapter. Could that be the reason it's not working. Not really, right?

Hi Karhl,

I reproduced the issue with the last Debian image. On Windows the device is
initially detected as RNDIS device but right after the RNDIS device disappears
and a serial device pops up. Will check further and let you know.

Thanks
Andrej

Hi Karhl,

some Windows installations does not recognise correctly the RNDIS devices. This
was actually already discussed in a USB armory group thread. Please follow the
solution decribed in [1]. Just tested and it works.

Cheers
Andrej
