Hi Folks,
Got an odd one here.
I need a USB host controller that can handle talking to a USB device that has 2 256 byte max packet sized bulk endpoints (1 in & 1 out).

Yep, I know that's non-standard, but I have absolutely no control over that end of things.

Can any of the 8 bit AVRs with USB host possibly handle that?

Been going through the data sheets but the host mode has me a bit confused. Some seem to allow a single 256 byte pipe and then restrict it to EP1, but I'm not completely sure about that.

Any ideas appreciated,
Thanks.

There are only two. What's more the AT90USB647 and AT90USB1287 share a single datasheet so it should be pretty easy to check what endpoint sizes they support.
