As expected no suport for Linux.

Bad. Can you do a full lsusb -v and show the output? I would be interested in in seeing if they use a known USB class / sub class. This enhances the chance to get a kernel driver for it. And even if there isn't a kernel driver, if they use a standardized class you can get the documentation from usb.org, which opens the way for an own driver (typical in user space, which isn't too difficult to do).

If you get the USB running in Linux under Wine you are almost golden. Then you can easily connect Wireshark to the USB interface and trace the communication, which allows to re-engineer the protocol they use.
If you only get USB running under Windows, then USB sniffing is a little bit problematic. The free sniffers like Snoopy Pro are rather bad and tend to fail, and the commercials aren't much better (but more expensive).

Woah did they provide you with that international mains plug adapter? Doesn't have earth and is one of those non polarized plugs. So you can plug it in with the adapter and the chassis can be live? Hope you're just using a proper IEC cable

There are some Blackfin dev board having same USB chip, look for isp1362bd. There are also some Linux drivers,
i think with some trick it will work for you.

Hum I don't know, the Linux come out of the box with the isp1362-hcd - ISP1362 HCD (Host Controller Driver) for USB , but it is only to work as host, working as a peripheral it's probably another history.
I really didn't spend time looking at it, so I may be wrong.
About support in Linux for USB peripherals that use isp1362bd may exist, I just didn't know any.

About re-engineer the USB protocol, I'm not saying that is not possible or hard, just don't know if is worth the trouble, probably the rs232 it's more productive, you don't need drivers like USB, just understand the protocol and make a GUI application for it.

Don't worry, that adapter, can't even be used, look that the photo, don't even know why they sent it ;-)
