Quick circuit help

For my 5 key, Are the diodes needed in this circuit? I'm thinking they aren't, but I know you need them for a matrix.

Since everything is on the same row you shouldn't.

that micro doesn't have support for USB, does it? (pick a micro that does...)

also, none of those diodes appear to me to serve any need.

For your purposes, configure the switch input pins as pull-up, and have the switches connect that pin to ground( or vise-versa). nothing else required.

Why is D1 present? It would be very abnormal. You should remove it.

Okay so since i posted this all diodes have been removed, also attiny24/44/84 will seemingly work with vusb, which i think will make it work fine. Thanks for the help though!
