usbd is part of the play.
it has to enumerate and recover from
errors. appart from that you can
export #u, but don't use another
usbd on it. one is enough.
just start your driver.
if you can, it may be better to
export the driver fs instead.

it might make sense to do the opposite. import namespace onto
the machine with the usb and run usbd there. (e.g. for a keyboard-like
device.) for a disk-like device, it may make sense to import the
disk at the disk level.
i've done both with aoe, importing '#æ' and '#l'. there are interesting
tradeoffs that depend an awful lot on what you're tunneling via 9p.

Does remote USB make sense? Would it be possible to boot
up a plan9 system on one machine, export its usb device to
another machine and run usbd there and have the second machine
make use of any usb device attached to the first machine?
Would the latency be too high?

What kind of USB device are you considering whose data can't be exported.
i.e. why not export the FS on the USB flash drive? I have a feeling you're
going for something else here, though. Perhaps USB audio or something
without persistent storage.

my experience is similar to Erik's. as distance grows it's better to
deal with a higher abstraction. there's less chatter and so not as
affected by latency.

For what it's worth:
VirtualBox has USB over RDP.
I have no experience with this, though.
Axel.
