USB is more like Apple's ADB than a RS232 serial link.  If or when it
is supported, it will probably be only as another bus to which devices
may be attached in the kernel.  USB interfaces will bear no similarity
to a 8250/16[45]50 UART.

I agree that trying to connect ISDN via an RS232 link is Wrong; but
you should blame the hardware designer, not the operating system.
