There might be, but if so, that's the business of the device's
own driver, not the usb driver.

Not if you use normal read/write to talk to usb endpoints (which
seems to me a Good Thing).  Normal read/write system call doesn't
have a timeout argument.

Again, if so, that's for the device's driver to set up and deal with,
not the usb driver.
