I initially dismissed it as completely fake. After all, it’s just a string of pin adapters, and you can’t get a flash drive to talk to some parallel port.

But then I thought some much more tape storage. What if 1 were to replace the crystal inside USB generate with a single of a significantly lower frequency, and then write a virtual device driver which implements USB applying the parallel port pins? This would, needless to say, make the USB device useless on a standard USB interface, however it appears like it will be achievable. And there’s also the query of “why on earth would you need to?”, but if you are the type to ask that question, you likely wouldn’t have seen it inside 1st location.

Do you have any insight as to why this kind of an approach would or would not deliver the results technically?

This reminds me with the hardware dongle, 1 of the numerous great creations in the copy-control industry. These days I feel copy-protection dongles are all USB, but there was a dat72 time when some lucky users had to daisy-chain multiple parallel-port doodads in order to run many protected apps at once.

As you say, there’d surely be some way to connect a USB thumb generate to a parallel port, but not with standard computer-store products. (No, you can’t just take a USB-to-parallel adapter and turn it around.)

I’m certain this sort of trick has basically been carried out a lot of times, to connect modern-day storage to legacy systems. I do not believe it’d be a enormous career for 1 of the modern-day easy-to-program microcontrollers (Arduino, etc). If you’ve got some 35-year-old industrial pc that still works fine except its moving-parts storage keeps crapping out when the mining dust or machine-shop shavings get into it, hacking up some solution to replace its ancient challenging (or floppy, or optical, or tape drive with Flash RAM is appealing.

There is additional than 1 part on the hack-as-presented that couldn’t possibly function, but what I instantly noticed was the green USB-to-mini-DIN adapter, which is likely a person of those standard adapters for connecting a USB mouse with a PS/2 port, several of which can normally be discovered within the desk drawers of anybody who’s been employing a PC for the last ten years.

Individuals mouse adapters are, as you say, just pin-adapters, containing no logic; you could in principle do the same job with paper-clips and tape. Mice that function with these distinctive green adapters all have USB and PS/2 compatibility built in, and use a person or the other depending on what they reckons they’re plugged into. I consider any in the green adapters will perform with any this kind of mouse, but they will not operate having a USB-only mouse, and they absolutely will not operate with USB devices in general.

This sort of factor is 1 on the standard causes of support people banging their heads on the desk.

Theorem: The guy who’s daisy-chained adapters so he can plug his XT keyboard into his iPad is preferable to the guy who’s managed to plug a PCI card into a memory slot by just pushing genuinely lto tape drives, truly hard.
