It requires the user to specify some model specific variables that  
can't be auto detected since the underlying serial protocol doesn't  
support that. So in essence what you're asking, can't be done (which  
you found out already).

Unless you can find someone willing to integrate the existing USB to  
serial implentation in the 'powercom' driver, the only thing HAL can  
(and apparently will) do is adding a USB to serial device node on your  
system. Given the remark above, I don't think it is worthwile to spend  
the time on that.

I will do that. Note that there is a newer generation of PowerCOM  
devices that is about to hit the market that uses the HID PDC protocol  
and therefor is supported through the 'usbhid-ups' driver (only  
development version so far).
