IF you can connect to the internet, you'll need to go to the Averatec support site and look up the driver downloads page for your laptop model and operating system. The link below should take you to a page (not Averatec's) that also has the drivers you need.
Download and install the Chipset drivers, as well as the drivers listed for Audio, Video, USB, and Network. It would be a good ideal to download ALL drivers listed for your laptop model and operating system and burn them to a CD for possible future use. Once those drivers are installed, you all of the yellow question marks should go away and your system should start working just fine.
If your USB ports are installed correctly and enabled in BIOS, you will see Universal Bus Controller list in the the Device Manager. Double-click your USB in the Device Manager and a dialog box will appear. Click on the driver tab and update the driver. To get to Device Manager right-click on My Computer>click on Hardware>Device Manager. If your computer has a built-in USB device and does not detect the device through the Device Manager, confirm that the USB is enabled in the computers BIOS and that the BIOS supprts USB devices.
Microsoft bought Eisenworld. Both the Eisenworld and Alohabob web sites have been shut down. You will NOT be able to update it. AlohaBob will be incorporated into the Vista update.
Try updating all your UBS drivers:
Go to your "Device Manager" (Right click on ‘My Computer', select 'Properties', click the 'Hardware' tab, click the 'Device Manager' button. Click the "Universal Serial Bus controllers").
If there is some kind of a yellow "Warning" icon superimposed on the 'UBS' icon there is your problem! If no "Warning" icons then try... One at a time... Double click on each of the devices that have 'UBS' in the listings. Click the "Properties" tab; look for any "Warning" icons Uninstall the DRIVERS for THAT DEVICE only. See instructions below. Click on the faulty driver and hit the remove button, follow the instructions given by the program. Shutdown, restart, the device will automatically reinstall by the "Found New Hardware" program.
Go back in to Device Manager and Update all the Items listed under "Universal Serial Bus controllers"
Well, appears that your configuration can handle 4 GB of memory. I checked the Acer website for upgrades for your model, and nothing appears to jump out which could solve your problem. A few appear to be possibly helpful, but some are for XP, not Vista. Upgrading "launch manager" might be a good thing.
However, Belarc tells me that on my Acer 5630 i have listed under "Bus adapters" the following: Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27C8 Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27C9 Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27CA Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27CB Intel(R) 82801G (ICH7 Family) USB2 Enhanced Host Controller - 27CC And, under "other devices", i have a USB Root Hub (5x). Obviously, the two match. I go to device manager to check them out, finding them under 'univesal bus controllers", to see whether they are all working properly, and and they are. In addition, opening "system devices" reveals something called a "plug and play software device enumerator", and that checks out to be working fine as well. Check your equivalent out to see if you find a problem to fix. Hopefully you will. Let me know how things go.
Check the USB properties if there are some errors at Control Panel> System> Device Manager> USB device. Install the compliment CD driver for USB devices. Also try placing the mouse into other USB port(s). Update your OS as necessary for device patches and if there's a need to install driver for the said mouse please install then.. Hope thos helps.
First, let's get the obvious/simple things out of the way, just to be thorough :) : Power off the PC, leave ten seconds, power on again then try it.
Have you tried it with another USB cable Have you tried it on another USB port on the PC (if you've been using a front port, try a back one & vice-versa - they're often controlled by different chips).
Assuming none of those work, the most likely cause is a corrupted USB driver. To fix this: * Make sure the camera's USB cable is not plugged into the PC. * Uninstall the Olympus software (Camedia Master) if you have installed it.
Now delete the C5060 device as follows:
* Go to the Control Panel. Double click on System. Click on the Hardware tab and then click "Device manager".
* Go to the View menu and click "Show hidden devices".
*Scroll to the bottom of the device list and expand the USB list. You will see some USB Mass storage devices.
* Go through the list: double click on one, wait for its properties sheet to open and look at the Location. It will have something like:
Location 0 (C5060Z ).
Hit "Esc" to close the property sheet. If it was the right one, delete it (select it with the mouse and hit Delete). If it was the wrong one, proceed to the next one.
* Close Device manager.
* Reinstall the Olympus software if you are using it.
* Plug the camera's USB cable into the PC as usual. If all goes well, you'll get the "Found new hardware" message and it will proceed to reinstall the driver, following which all should be well.
If none of your USB ports work on your PC, then it could be possible that your USB chip set controller driver got corrupted. I would 1st check the device manager at the very end of the list indicating "universal serial bus controllers", check to see if their is any exclamatiom marks or question marks indicating a possible driver problem. At your own risk you can try refreshing your USB chip set, I would highly recommend to check to see if your keyboard and mouse is a Non-USB interface if they are then refreshing the usb ports will disable your keyboard\mouse no navigation avail. If this is the case then I would try a different route by reinstalling your USB drivers. On the other hand if they are P/S2 interface's then you can refresh the USB controller; Go into the device manager at the end of the list "universal serial bus controller" click on the (+) symbol and locate any listing that includes "universal host controller" you may have more then one, once you locate them right click and delete them. Once deleted restart PC and windows should refresh the USB controllers. Please note this only applies to Windows 2000 & XP.
