Requirements for USB 2.0

[5p33dy]

I recently purchased a USB 2.0 PCI Card made by BELKIN. The box says that the card requires PCI 2.1.

My computer is quite old, 1998, so I expect that it's motherboard may not be PCI 2.1 compliant.

The card works but only at usb 1.1 speed (eg 1.5 MBs)
How can I confirm that my motherboard isn't PCI 2.1?
Do all USB 2.0 ports require PCI 2.1?? If so, WHY!!??

I have Win XP SP1 installed, and the card is reconised as being USB 2.0.

I have now been able to confirm the following:

By Motherboard is PCI 2.10
By Windows version (XP SP1) is USB 2.0 compatable
The USB PCI card I installed is USB 2.0
The device I am connecting is USB 2.0 compatable
Windows reconises both the USB port and the device as USB 2.0, but still connects them at USB 1.1 speed.

This is so, so, so infuriating.
I don't think I'm going to be able to fix this, but I hope I'm wrong.

Go to the device manager and see if there are any error codes.

Everything looks ok under device manager, the card contains 3 ports and 3 controllers. One controller is a high speed (USB 2.0) one and is listed under "Belkin USB 2.0 High Speed Host Controller" this controls all 3 ports.

There are also 2 additional controllers both of which are USB 1.1. One of these controls 2 of the ports on the card, and the other controller controls the remaining port. This is a bit weird I know, but it's all correct.

I also have usb 1.1 or 1.0 controller on my motherboard which has 2 ports.

I scanned my system using "Sandra Lite" and this is what it told me:

General Information

As you can see I am connecting a USB 2.0 device to a USB 2.0 port but the connection speed is 12Mbps.

HELP!!

Is this the device?

[5p33dy]

No, that's not it.

This is it:



I don't think it's the device that's causing the problem, I'm also getting the same problem with my other USB 2.0 device.

It appears that all Belkin USB 2.0 cards have drivers, even for WinXP.  Driver version should say:  2.1.10

USB 2.0 PCI Card Drivers

[5p33dy]

Thanks for the sugestion of driver updates. I wish I could say it solved the problem, but it didn't.

The new driver installed (I checked the version number) but it has made little difference.

I don't think I'll be able to fix this now, I just have no idea where the problem is coming from. Prehaps my system has an inherent incapability to function at USB 2.0 speeds, who knows. I don't normally like to give up on computer problems but I think I'll just have to live with slow USB.

I'll check back here a few times to see if there are any more suggestions and then I'm giving up.

Sometimes I think computers are just to complicated, I prefer simpler thinks like fixing bikes or playing Sudoku.

Use it on the computer (LOL).

One thing left to try.  Change card to different PCI slot.

[5p33dy]

PCI Slot change didn't help.
I've been fiddling with my diagnostic program again, this is what I came up with:

PCI Bus(es) on Hub 1
Version : 2.10
Number of Bridges : 1
PCI Bus 0 : PCI (33MHz)
Multiplier : 1/3x


USB Controller 1
Model : Intel Corporation 82371AB/EB/MB PIIX4/E/M USB Controller
Version : 1.10
Interface : UHCI
Channels : 2
Speed : 48MHz
Supported Speed(s) : Low (1.5Mbps) Full (12Mbps)
Legacy Emulation Enabled : No

USB Controller 2
Model : Belkin Research and Development Labs uPD720101 USB OpenHCI Controller
Version : 1.00
Interface : OHCI
Channels : 2
Supported Speed(s) : Low (1.5Mbps) Full (12Mbps)
Legacy Emulation Enabled : No

USB Controller 3
Model : Belkin Research and Development Labs uPD720101 USB OpenHCI Controller
Version : 1.00
Interface : OHCI
Channels : 1
Supported Speed(s) : Low (1.5Mbps) Full (12Mbps)
Legacy Emulation Enabled : Yes

USB Controller 4
Model : Belkin Research and Development Labs uPD720101 USB 2.0 EHCI Controller (Version 1.0)
Version : 2.00
Specification : 1.00
Interface : EHCI
Channels : 3
Companion Controllers : 2
Supported Speed(s) : Low (1.5Mbps) Full (12Mbps) High (480Mbps)
Addressing Support : 32-bit
Legacy Emulation Enabled : No



I don't really know what all this means but it seems my Front Side Bus is 100MHz and my PCI bus is 33MHz.
Are this figures normal? Can USB 2.0 work at this spec?

As you can see my USB 2.0 controller lists 480Mbps as a possible speed, but something is holding it back. Quite what that something might be is proving difficult to find out.

I'm going to try the card in my old computer tomorrow and see if it works in that.

[5p33dy]

I was fully expecting the card to work in my older computer, but no, it didn't. I got the same problem, only USB 1.1 speed was available. My other computer is running a completely different OS (win 98 SE) so I think I can rule out OS issues.

I think  the problem must be one of the following:

There is a minor defect wth the card.

I'm setting the card up wrong.

Both my USB 2.0 devices aren't really USB 2.0.

The first and third option seem unlikely, but then again so does the second.

I wish I had kept my receipt........

I'm certainly going to steer clear of Belkin products in future, just in case it's their fault.

1.  I think so.
2.  You tried the latest drivers.
3.  I know the JumpDrive is 2.0, I looked it up.
4.  Never had a problem with Belkin in the past.  Maybe they've changed manufacturers and quality is down.

I've got an old computer and my No-Name PCI USB 2.0 card works just fine with my Lexar JumpDrive and my no-name 2.5 hard disk drive.

Belkin has a good warranty and will probably exchange for a new one.
