USB 2.0 - How to get it working

[Lars-Erik Østerud]

My P4PE board has 3 USB 1.x controllers/hubs, and 1 USB 2.0.

But they say that one USB 2.0 will provide USB 2.0 support on
all USB ports (does snyone know how this acyually work).

I have installed Win98se USB 2.0 driver (OrangeWare I think)

But still my Canon i850 printer that supports USB 2.0 shows
up one one of the USB 1.0 hubs, and when I run an info program
(System Information Viewer) it's listed as an USB 1.1 device.

HOW do I get the printer to use USB 2.0 on my system ?

HOW can I see if a device is using 1.1 or 2.0 ?

The answer is, it really is just a USB 1.1 device. Check your Canon
manual and compare to the definitions listed below. Notice that
the terms are a marketeer's dream :-( It is Canon's way of saying the
printer can be connected to a USB 2.0 port, but you won't benefit
in performance.

The USB terms are defined in the USB_20 spec.

Low-speed USB operation at 1.5 Mb/s. See also full-speed and high-speed.
Full-speed USB operation at 12 Mb/s. See also low-speed and high-speed.
High-speed USB operation at 480 Mb/s. See also low-speed and full-speed.

These definitions were extracted from page 34 of this doc:

OK, but how would a 2.0 device show up ?

Will it show up on one of the regular hub's (just like a 1.x device) ?
How can you see the speed (the utility I found was not that easy) ?

If you have a utility for "seeing the speed", stands to reason all you need
is a USB 2.0 device. An external hard drive is a typical example. Avoid
using a hub if possible.

No, I don't have a good such a utility - Do you now where to get one ?

BTW: What is then fastest to use, Parallell port or USB 1.10
I switched to USB because I though it had USB 2.0

The one not-that-good utility I found callthem 1.00 SLOW and 1.10 FAST
Maybe the utility os not USB 2.0 aware at all. Got to get a better one

I haven't read of any utility that measures the active transfer rate.
Would be cool if there was one.

All I am aware of, is looking in the Device Manager for the USB2 Hub or
the word Enhanced on one of the entries, as evidence that a USB2 driver
has been installed.

As for the parallel port, it is good for about 1MB/sec, which is 8Mbits/sec
and is in the same ballpark as the USB 1.1 rate of 12Mbits/sec.
Where the difference will be, is the mechanism used to feed the two
interfaces. One could be more efficient than the other. The only way
to tell, will be to print a graphic page and time it with a stopwatch,
to see which interface completes the job first.

Oh... There is both an USB 2.0 Root Hub, and an USB 2.0 Contoller
But only one (still they say that should give USB 2.0 support on all
6 USB ports; divided into 3 USB 1.1 Root Hubs on 3 USB 1.1
controllers). I'm not sure how this works though. Anyone know?

 

[Robert Hancock]

Yes, only one enhanced (EHCI) controller entry will show up. Any devices
plugged in that are USB 2.0 High Speed compatible should show up as
connected to that one, anything else shows up as connected to one of the 3
other entries. I believe it was arranged this way to maintain compatibility
with older OSes that did not support USB 2.0..

Maybe it looks like this. Either a USB 1.1 or the USB 2.0 controls
a port. The USB 2.0 is shared over all the ports, so if all 6 ports
do USB 2.0 transfers simultaneously, each gets 80Mbits/sec bandwidth.
The USB 1.1 controller is shared over two ports, so if two ports on
the same controller transfer simultaneously, they each get 6Mbits/sec.

Thought so, but on the properties for the USB 2.0 hub there are no
listing of connected devices (on the USB 1.1 hubs there are always a
list of connected devices and their bandwith and power consumption)

Make up your mind. You do or don't have this mythological utility?

[Lil' Dave]

Nope, it don't say that it is capable of USB 2.0 operation speed.

&section=10213

Use a device that REQUIRES USB 2.0 for proper operation. Say for instance a
USB 2.0 hard drive. If you see no apparent response difference between
that and your onboard hard drive, its using the 2.0 interface. USB 1.1 will
be very apparent as it will be very slow.
A less apparent difference, but apparent ot the experienced user, would be a
scanner in the same scenario of 2.0 vs 1.1 use. A PSC, like an HP 750 is an
example. It goes for the same price as the list price of your printer by
the way.
If you can connect your current printer to the LPT port, print a HIGH color
full page photo and time the print time; then connect to USB and do similar.
If the times are virtually identical, its using USB 1.1

All USB 2.0 ports are capable of USB 1.1 use. But not vice versa.

I have one, but it's not very easy to use, and I'm not sure if it will
show USB 2.0 devices (it' calles USB 1.0 for SLOW and 1.1 for FAST)

 

[Lil' Dave]

Which has no bearing on any question you asked, so why distract with it?
