I think I'm beginning to see the 'logic'. It might have been sufficient to look at the "dmesg" output, though. It might even give you the USB ID of new devices.

A second after plugging the device does autoswitch its mode. Look for:

[ 434.700025] usb 1-5: new high speed USB device number 7
...
[ 435.839094] usb 1-5: USB disconnect, device number 7
...
[ 436.280028] usb 1-5: new high speed USB device number 8

I strongly suspect that usb_modeswitch interferes with the process and prevents the switch.
Yet it is not clear why there is an autoswitch in Linux only and not in Windows. Maybe some driver action (or non-action) triggers that. It would be interesting to see what kind of effect a blacklisting of usb-storage might have.

Anyway, as I said, if the match string "uPr=WCDMA" is appended to the name of the config file, there will be no more interaction with the Blade. For this, extract all files from "/usr/share/usb_modeswitch/configPack.tar.gz" to the same folder and rename "19d2:0083" to "19d2:0083:uPr=WCDMA". At your liking you can repack the files - or not.
