I'm trying to connect a digital camera and media reader to a USB port. It won't recognize either one. I disconnected the printer and that port didn't work either. I took both items to another computer and it recognize them. Could this be a 1.1 / 2.0 USB problem? If so, how do I remedy this?

Hard to tell with the info you provided. If the camera and reader are USB 2 and you have USB 1 ports, you are out of luck with the current setup. You can install a USB 2 PCI card to fix this. If this is not the case, please provide details about the computer, the camera, the media reader and what version of Windoze you are using....

Also check the BIOS USB settings.....sometime you need to use the "assign IRQ to USB" in order for it to work correctly.

Sorry it took so long to get back but I had to wait for the puter to be delivered to me. It is a:

Windows 2000 Professional
AMD Duron 1300
256 MB sdram
2 - 20 GB HDs
ECS K7S5A motherboard
64 MB video card TNT 32

The problem is that the puter recognizes the Dazzle Media Reader being connected (USB). The Dazzle software was pre-loaded. When it is plugged in the box comes up saying it is searching for the drivers. Next another new hardware found box comes up that says disk drive. The puter just sits there and you can't get out. You have to hit the reset button. If the reader is left in during the boot up, the computer freezes before it comes alway up (Windows 2000 Professional screen with the action bar about half way). My father-in-law (the owner) has his printer connected to one of the USB ports and that works great. I tried that port without success for the reader. I cannot find the BIOS setting for assigning an IRQ to the USB. I went thru the setup three or four times and it is not there. That's it....any help and I would be a hero to the FATHER-IN-LAW...thanks in advance....

I would say that when the box pops up looking for the disk use the browsee function topoint it toward the folder where the drivers reside (or pop in the disk...even if you have to copy the driver folder to a floppy).

Well, I would if I could....the box says it is searching for the drivers and then goes directly to the next box thats says disk drive. It does not give me a chance to point at the location of the driver. It acts as if it found the driver but just won't finish. The system has a C: and a D: drives. I tried put the drivers on each hard driver without any success. I put the Dazzle Media Reader on a machine that has USB 1.1 and it worked just fine. It gave me a message that it would be working at the slower rate (USB 2.0 vs USB 1.1). Tonight when I get home I am going to try a USB hub that has power to see if that is the problem. Thanks

Well, I've tried just about everything. I upgraded to a newer model of the motherboard, I've tried using a USB hub, I have deleted the USB drivers and reloaded them. I have had some success. A few times it actually recognized the media reader. When I turned off the PC, it would not recognize the reader. The machine wouldn't even boot all the way up. It would get the little blue bar just past half and stop. I would then unplug the Dazzle media reader and hit the reset button. The machine would then work great. We tried plugging the camera in direct and funny things would happen. The machine would just reboot on its own. But somehow the problem fixed it self, at least we don't know what we did. The camera now works everytime we plug the puppy in. The media reader still doesn't work. We tried the Dizzy (Dazzle) media reader in another machine and it worked great. When we plugged the reader in after the machine was up, the PC would become very slow. It would take My Computer about 2 minutes to come up and would only show the permanent drives. The PC would not shut down, you had to hit the reset button.

Any more suggestions would be appreciated.....thanks

I didn't see that you have tried installing the driver in Safe Mode, so you may want to do that. Probably either from Device Manager using Update Driver or from the Hardware Wizard after Removing whatever is installed now...

First off, using a usb2 device on usb1.1 (http://www.everythingusb.com/usb2/faq.htm) should only create a problem relating to the speed of the connection and not to whether the device should work or not. Other problems are probably bios or driver or IRQ related and not USB2/1.1 incompatibility.

In general, the sequence of installation is very important with USB devices and the drivers should just about always be installed prior to connecting the devices. If not then it is hard to rectify any problems/conflicts that ensue.

I think this is not quite the same as "ghost drivers" with other hardware. Also deleting them from the device manager (in normal or safe mode) still leaves the pointers in the relevant inf files. Possibly deleting the relevant inf file is the only way to get back to "square one" and "clean install the drivers" - and I'm sure I've seen this as a fix somewhere - but can't for the life of me find it now.

To get full USB2 functionality either third party drivers would be required or with Win2K/XP, there is a MS update that should be made available from the Windows Update site - as long as a recognised USB2 device is attached at the time.

What is actually showing in Device Manager under USB? Some unrecognised devices maybe??
