I have a panel with a rotary switch and several toggle switches. I need to sense the switch positions and output them via USB. Any ideas of how to implement? Thank you, Dale

The FTDI FT2232D is a USB peripheral chip that advertises a bit-bang mode.
That's all I know about it.
But it may be worth checking out.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.

here is a whole bunch of USB interfaces to have a look through:

These work with a little work.
How much work are you willing to do ?

I'd map each switch to a bit stored in a register, file, etc. somewhere. Then output the register, file, etc. to USB (or whatever) either on some set schedule or whenever a bit changes.

Rip apart a USB keyboard and use it?
USB game controller?

Get a parallel to USB adapter. One with EPP or ECP support.
