Hello, I wrote:

Please, no.
What exactly 'no'? ;-)
No one-port hubs I guess -- they are pointless. Though e.g. MUSB
driver creates one -- I guess to impersonate a transaction
translating high-speed hub...
... then the root hub emulation is completely pointless.
It isn't. We always should emulate the root hub. The root hub
is part and parcel of any USB Host. Even the one-port one.
Hm, maybe that's what USB core thinks (because UHCI/OHCI/EHCI all
have it) but e.g. MUSB doesn't have the root hub registers...
Oops, I stand corrected. Even USB 1.1 specifies that it must be a
part the host...
