Is it the fact that one time it is detected as USB device and second

You can see some example of it here, the Huawei E398 does the same.

"usb_modeswitch - switch mode of "multi-state" USB devices"
When you insert it it emulates a cdrom drive with a disk in it so you
install drivers on windows, then after driver installation the driver
usb_modeswitch:es it to a new device with a different product id.
