Yup, USB hosts (as opposed to the much dumber OTG) were "only" present in
the following (old) devices built-in:
Fujitsu-Siemens's standalone WM2003SE+ PDA's (PL720, N560 etc)
Toshiba's E750, E800, E830
I've thoroughly tested external USB keyboards with my PL720; most of them
worked OK.
These devices are, of course, old and not recommended - not even the latest
N560 with the latest ("unofficial") upgrades.
I've also elaborated on the old, CF-based USB host cards - see my blog.
HOWEVER!!! The latest HP iPAQ 21x does have USB host functionality built-in.
While there still isn't a cable / cradle that makes this functionality
accessible, I think it's a sensible move to get the device as it's really
cool. See for example the Brighthand and the MobilitySite forums (
http://forum.brighthand.com/forumdisplay.php?f=1333 ) for more info. I'll
also devote a bigger article to the iPAQ 21x in my blog in the near future.
