[time-nuts] [OT] more (low cost) PC<>ad-hoc IO - even lower cost.

Yep, that works.

Many of the "Softrock" SDR kits use that method ("Bit Banged" USB) for
control of the local oscilator, filter selection and other IO.  Works
well, when it works.  When you get the drivers mismatched, it can be
hell!   It's also limited to the low speed protocol, so there are some
limitations, but for the minimalist aproach, very good.


Is the basis for that, and open source too, also with an active (and
interesting) user forum.

Seems they had to change the name from AVR-USB to V-USB to avoid
trademark conflicts with Atmel.

Enough from me.

This implements USB in the software of an AVR - no special USB chips
