We were updating the firmware by means of the tool given in "ehsx_rev03.001_arn0000051" (the complete name of the executable is "ehsx_gwinswup_rev03.001_arn0000051.exe"). We used ASC0 at 115200 .
We got success in a couple EHS6T-USBs.
But one of our EHS6T-USBs got a failure in the updating proccess and now it's unusable.
*It's doesn't repond to ASC0 AT cmds
*When I connect an USB cable, I can't see the "Cinterion EHx USB Com PortX (COMXX)" list in the Windows Device Manager (section Ports (COM and LTP) ) . So is not possible to send at commands by USB
