Subway USB and AmigaAMP

What's the volume name of the usb-stick? devs?

[kolla]

It's UMSD:

I meant volume name, not device name

[kolla]

It appears as FCDF-408A (the name), UMSD, which I think is the volume, isnt it?

Yes, FCDF-408A is the volume name, and that should not be harmfull.
As for apostrophe, you could try using the program "keyshow" (iirc) to find it on your layout.

Another guess from me - poseidon has this habit of playing sounds when devices is inserted/removed - maybe it holds the audio device. There's a setting somewhere to turn that off.
