Any ideas for solving this?

We could bump up the MSRV? We haven't published a crate yet...

Also, instead of doing this uppercasing manually, you could just call c.to_ascii_uppercase(): https://doc.rust-lang.org/stable/core/primitive.char.html#method.to_ascii_uppercase (and use map instead of a for loop)

Any suggestions for a MSRV?

Might as well bump it to 1.88?

How about:
rec::Usb { _marker: PhantomData }.reset().enable();

nit: move this closer to where it's first used.

Do we need to hang on to these pins? Doesn't looks like they get used anywhere. Could just consume them in the new function so they can't get used anywhere else (e.g. SPI driver does this).

I dont think we do

this is out of date. how about just using the Debug derive for this?

We actually don not use the pins for anything once they are put into the struct. As in we have no release method. Should I remove them from the struct?

fields `pin_dm` and `pin_dp` are never read
`UsbDevice` has a derived impl for the trait `Debug`, but this is intentionally ignored during dead code analysis
`#[warn(dead_code)]` on by default

Yep. Latest changes look good.
