Hello Wolfram,

This handles only part of the risky addresses. I once worked on a device
having an EEPROM using 32(!) addresses in the range from 0x00(!!)-0x1f.
And yes, because it was the only device on the bus, that actually worked.

So, the lower boundary should also be removed IMO.

Good to know, I will send a new patchset which takes the lower bound into account.

And I'd much prefer a flag like 'R' which represents 'risky' better.

I disagree here, the i2cdetect program is already using the '-a' option for scanning risky addresses. I think we should keep consistency between options and keep this option named '-a' for the other tools. As per i2cdetect's man page:

-a    Force scanning of non-regular addresses. Not recommended

Best regards,

Romain.
