USB can't even keep track of 1 device moved between two ports, so I don't
know what your 256 port chatter is even about.


So, you're clueless, stupid & bitter. Got it. All the computer is
doing is telling you that the device wasn't used on that port before.
Try swapping an external RS-232 modem & RS-232 mouse on an old PC and
you'll be doing all of the work yourself rather than just see a popup.

you don't know what you're talking about is the problem here.

take for example an epson 1680 scanner, or tons of other devices.

moving it will require a reinstallation of the driver, and you can't
just point windows at the location of the drivers, which are already
there. Printers are notorious for this bullshit too.

Back to the scanner- if you use with with the SCSI interface and change
IDs it doesn't require a reinstall.

something with USB and how things use it is completely retarded.

RS-232 never claimed to be smart, easy or anything.

USB does, which is a big lie.
 
I've never seen this with USB. USB is keyed to the
device's description -- not to a specific port.

Wrong.

If I plug my iRiver H120 into any USB port on any computer, it's supposed to
recognize that the device is a hard drive, and install the appropriate
generic driver to communicate with it.

If the device isn't "generic", the system will look through its "records"
for the correct driver. If it finds it, fine. If not, it prompts me for the
appropriate driver.

I assume what Michael says about Epson screwing everything up is true. I've
never installed an Epson product.

wrong.

the port a device is on is somehow a big deal. Why? I can't explain why
people do stupid things, but they do.

Intelligent technical people developed stuff like ethernet, where you can
move everything around and it works.

dumbasses made USB, where that's not the case, and you end up with stuff
like CDs with WARNINGS IN CAPS!!! DANGER INSTALL DRIVERS BEFORE PLUGGING
IN DEVICE.

I've never seen that warning on a parallel port, serial port, starlan
adapter port, arcnet adapter port, tokenring port, FDDI port, ethernet
port, SCSI port, Fibre Channel port, or anything, ever period.

USB = total shit.

I used a dumb terminal before I had a complete computer, so I'm no

What I don't understand is why we need a 480Kbps interface to connect
a keyboard or even a mouse. My maximum data transfer rate, as a
two-finger typist, is only about 2 bytes per second, error correction
notwithstanding.

I'm serious. I find it extremely annoying when I encounter an
application that won't run because it can't handle a USB keyboard or a
USB mouse. IMO there was nothing wrong with the PS/2 or AT keyboards
or mice, or serial mice for that matter (I'm still using a serial
optical Mouse Systems mouse), so I see no reason to introduce an
additional complication. USB is fine for high speed (or "full" speed)
peripherals, but I'm not going to waste a port on a keyboard.

You've lost me.

A Windows or Mac program knows nothing about the interface used by a mouse
or keyboard. It doesn't even "see" the device! The operating system sends
the program messages with keyboard data or mouse positions.

Most computers have no fuse, outside the power supply so the full
output on the +5 volt rail is available. I sold a used XT computer
years ago. the guy got it home & fired it up. The keyboard cable
caught fire, and melted the +5 volt line all the way from the five pin
DIN connector to the strain relief on the keyboard.

I've seen the USB 2.0 specs, and they're beyond unbelievable. You'd think
what appears to be a simple interface would take only ten pages or so to
define, but it takes 10 or 20 times that.

And the code is far worse, I'm told. There's a reason why
Firewire does so much better than USB2 at moving lots of
data....

But I agree it is a great success at the universal aspect....
