The AT90USB1287 has a USB OTG miniHost.
This can connect to a single USB device, but not to a hub.

thank you both for these leads. i don't much about usb but i have a
usb peripheral (a sensor that has only usb) i'd like to use. much to
learn.

In this case, you need a host, not a device so the
AT90USB1287 should be a good choice.

AT90USB1287 is too expensive as a device.
Where can I get pricing data for AT90USB82?
DigitKey has no info on it.

It is too early, and the AT91USB162 will be available before the 82...

162 is not in DigiKey either. I know 10K price is around $2 (162) and
$1.5 (82). But customer wants to know 100s and 1K as well, before
committing to a design. Will they be available in 6 months? I am
trying to avoid an usb bridge, or an ASIC solution. Our current
design is AT90USB128 ($7) and atmega329 ($5), but they are too
expensive.

Next phase could be AT90USB162 ($2) + ASIC LCD ($2). I wish to stay
with AVR, but I just can't flight the cost.

My dream chip is a 32 pins USB w/ LCD (12 segments x 4 common), as
long as it stays below $5.

This is intended to be my personal opinion which may,
or may not be shared by my employer Atmel Nordic AB

I tried very hard to convince client to go with Atmega329 (169 is
obsolete).
But I am going to fight harder to go without, since we don't need more
than 8K flash.

Atmega329 is still the right solution for first pilot run, but not for
final runs.

For now:
AT90USB82 ($1.5 8K) + NXP PCF8576D ($1 LCD 40x4 seg) might work.

Do you think the USB82 would be ready in 6 months?
If not, I might have to change again.
