USB 2.0 and USB 1.0

Topic

New Reply

Hello:

Today I had installed 2.0; however, the IT person left the USB 1.0 as I had two usb cables plugged into the USB 1.0

The problem that I am having now is that the two items that use the USB 1.0 does not work. What can I do?

Thanks

Check in Device Manager whether your IT person has disabled the USB 1.1 devices? (Many ways to get to it, easiest, perhaps, to do Start -> Run and type DEVMGMT.MSC in the box, and press Enter).

I would recommend to reconnect all your USB devices to USB 2.0 ports (usually USB 2.0 card has 4 ports). If you do not have enough USB 2.0 ports available, consider to acquire USB hub – they are inexpensive. (Some monitors have USB hubs built-in, for instance – maybe your monitor has one also?)

Usually USB devices have no resource conflicts; however, it is hard to troubleshoot your problem. First, try to disable connected USB devices by clicking an icon with green arrow (see attachment, “Safely remove hardware” wizard). If you do not see an icon, you can download and use The DevCon command-line utility. Then use guidelines described in Is there a way to “Safely Remove Hardware” from a batch file?.
After this step, physically disconnect and reconnest your devices, and look does Windows recognize your devices (“Add new hardware” wizard have to start automatically in the background, and you will see information baloons in the System tray). If this does not happen, use DevCon to check if your USB 1.1 and USB devices were installed at all.

Once again: in my opinion, it is not worth to troubleshoot this problem.

Hello JohnGray, Kaplinb:

JohnG: When I follow your instructions I see the following:

Sis 7001 PCI to USB Open Host Controller – I see this twice
USB Root Hub – I see this four times
ViA Rev 5 or later USB Universal Host control – I see this twic
VIA USB Enhanced Host controller – I see this once

I don’t know what to look for when looking at the Universal Serial Bus Controller.

Kaplinb: I have done just that, I have moved all USB cables to the 2.0, I was told that in the IRQ there is not enough sharing space, so that is why an individual would loose the connection to use the USB 1.0. All my device work in the 2.0

To anyone else who may stumble on the same situation, check out http://www.usbman.com, look for customer/retail section. I saw a lot of good topic about devices not working.

JohnGray: If you can get back to me about the Serial Bus controllers, that would be great. I just want to know why this has happend.

I was interested to know if you have any red crosses on any of the USB devices – if not, my theory that they might be disabled does not hold!

Hello JohnGray:

No Red crosses seen, after doing some research I found that I could boot up in safe mode, and do some searching. I think the reality is with the IRQ my computer is about 4 years old, she running on a 1 gig up from 768.

I read some where today that once you install the 2.0 usb card, a lot of times the 1.0 card will not convert to the 2.0. It is a fact that I will just have to tollerate, but I just want to know why.

Also, can you confirm for me why the IT person would install the 2.0 card upside down. I spent hours trying to figure out why my Palm and other handheld devices would not work, I could not even insert them into the 2.0 slots. Unitl I turned the Usb cable end upside down, which did allow the USB’s to get inserted. Is this normal?

Thanks dillon

How could it possibly be installed upside down and still work? Why could it not be that the USB add-on card has the ports in another direction than the built-in ports on the motherboard?

And if you add an USB card with 2.0 support, why would older ports on the motherboard “convert” to 2.0?

dillon,

See Argus post regarding installing the card upside down. I don’t see how?

The other item is that if you install a USB 1.1 device in a USB 2.0 card, The device will still only run at the 1.1 rate and not at the 2.0 rate. The device will still operate OK in the 2.0 card and there is NO conversion that takes place.

So USB 2.0 is backward compatible but USB 1.1 is not forward compatible, of course.

Argus: I am not a techie of any kind, when I purchased my computer, I had a bluetooth usb that would always blink a blue light on top of the BT. Now I have to turn it upside down, so that I can insert the BT device.

There could be a great possibility that the “A-Byte Card” is made that way. Since I have no Techical experience with motherboards, I would not have known this, that it why I posted my questions on the board. It is called learning.

Viking: Thanks for your explanation.
