Which one? Sweex is (in)famous for changing the internals of their  
devices, without changing the part numbers.

Unless it works with the 'blazer_usb' driver, you're most likely out of luck.

The above is just a generic USB to serial converter. What we really  
need is the underlying serial protocol that is used. I very much doubt  
that Sweex will be able/willing to tell which is used. You could try  
to reverse engineer the protocol by snooping the communication on the  
USB port between the (bundled) Windows driver and the UPS. Search the  
archives for tips on how to do this.

Best regards, Arjen

PS  In the end it is probably a lot easier to ditch this device and  
buy something that is supported out of the box.
