If you want to run spooky software then buy the 5Mhz Spooky2 generator. There are some hardware differences, I suspect MH do a special line for spooky. I think they have sold in the region of 15,000 of them.
With all these MH 2300 the USB to Serial is a Silabs CP2102 which defaults to bus powered. If the mains or power supply fails and the USB is still going, as in a laptop, then the CP2102 can be cooked. I have a utility from Silabs which changes a bm attribute from 80 to C0 which means it is self powered so can't be damaged that way.
I will attempt to attach it here
