That's good - let me know how it goes, and I'll update the driver accordingly.

Well, I hope it works.  Some people have reported USB timeouts, which I've been
unable to figure out.

It's not really a 2540 (I think).  The firmwares contain a string that appears
to be the model number, but for the 2000 and 2540 firmwares, it is "DEC2540-t",
despite the firmwares being different.  It's confused me on the odd occasion
too.  The 2540 actually uses the X firmware.
