An AVR itself. ;-)  There are a number of software-USB solutions
around for it (including an Atmel appnote).  However, they all are
low-speed USB solutions.

I don't assume there are any hardware USB solutions in DIP packages.
Why would one really want these (i. e. what would be the selling
argument for the vendor)?  Many amateurs have been soldering things
like FTDIs or PDIUSBs before in their TQFP or SO packages, so it's not
that SMD would be a serious hurdle even for them.

Depends on what you want to do with USB, is it to talk between a PC and the AVR?
Then you can use USB to Serial bridge boards like these:

Or are you wanting to talk to some other USB device? Then perhaps something like this:

All these modules are in DIP/breadboard format to make it easy to prototype.. But they are just the SMD chips etc placed into an easy format..

Hope that helps..
