Relative to current code this addresses a number of FIXME's by assigning

USB 2.0 leverages companion UHCI or OHCI host controllers for full and

Add a tty close callback. Right now if a guest device that is connected
to a tty-based chardev in the host is removed, the tty is not closed.
With this patch it is closed.
Example use case is connecting an emulated USB serial cable in the guest
to tty0 of the host using the monitor command:
usb_a
This fixes a segfault due to buffer overrun in the usb-serial device.
The memcpy was incrementing the start location by recv_used yet, the
computation of first_size (how much to write at the end of the buffer
before wrapping to the front) was not accounting for it. This causes the
