Yet, the CBM devices already have internal drives.

Short and crisp answer: no.

Longer answer: you could of course scan the bus with the "usual" device 
numbers, read the device type by sending a "UI" command and reading the status 
channel (which gives something like 73,VC1541....,00,00) - from which you 
could look up in a database how many drives are on the device.

So, no. And then, scanning the bus at the beginning might not be enough - 
drives can be switched on/off. So it would have to be done every time the list 
of devices is requested.

My approach would be to just return the standard devices for the platform, not 
showing drives at all. IIRC the CBM dual drives search both drives for a file 
on open, and use the last used drive if none is given on a create - so no real 
problem here.
