intersense: Failed to set control word on \\.\COM1

[OueOue]

hello,

i try to use a wireless iCube3 by intersense. however I cannot connect to the station even with devicetool.

the logfile isense.log states :

Failed to set control word on \\.\COM1 (Paramètre incorrect.)
Failed to get memory block at 0 for UNK1-3
Failed to set control word on \\.\COM2 (Paramètre incorrect.)
Failed to open \\.\COM3 (Le fichier spécifié est introuvable.)

"\\.\COM1" seams strange to me. any idea what I have to change and where ?? many thanks in advance !
