The ones I know about have a peripheral controller, not a host controller. There's a recent iPaq that uses OHCI on a pxa27x to contact an on-board bluetooth adapter. But AFAIK, PDAs with an USB host _connector_ is pretty rare. (There's a CF/IO card adapter I've seen, but that's not quite the same.) > and even recent windows > CE devices frequently list USB host capabilities... (Or USB on-the-go > which is similar, AFAICT). Well, you may be watching those WinCE devices more closely than me, but all I've noticed in that respect is spec-ware support for host side capabilities... with even that being scarce. I'd be glad to see that improving though! For USB OTG devices, a Mini-AB connector can act as either host or peripheral; and can switch roles later. Hub support is optional, so it's not necessarily as flexible as one might like. But yes, once that starts to catch on, it should be interesting. - Dave
