Usually, when you buy any hardware the drivers come along with it on a disc. If you lose the driver disc you can always download the necessary drivers from the manufacturer's website. But what do you do when you are not sure of the manufacturer of the hardware? Well now you will know what to do.

Open Device Manager (Control Panel>System>Hardware>Device Manager) The hardware whose drivers are missing will appear as Unknown device, so it's easier to locate the device. Right click on the unknown device and click on Properties. Under the Properties window click on Details tab and select Device Instance Id from the drop down box. You should see a code similar to this: PCI\VEN_8086&DEV_27DC&SUBSYS_30868086
& REV_01\4&1E46F438&0&40F0 In the text above the Vendor ID and Device ID will always be in the same place for the driver Vendor ID = 8086 and Device ID = 27DC your numbers will be different. Once you have obtained both the IDs, proceed to PCI Database. There you can either search for the vendor from the vendor ID or directly get information about the device along with the vendor name by searching with the device ID. http://www.pcidatabase.com/
b>Windows 7 First, please disconnect all USB devices and then perform the following steps:

Click "Start" button, type "devmgmt.msc" (without quotation marks) in the "Search" bar and press "Enter". Click "Continue" if necessary.

In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".

Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".


Then, restart your computer and Windows 7 will reinstall all USB controllers automatically. Hope this helps. b>

I hope you find this information useful and if you need any further assistance,
please feel free to contact me and let me know. I hope this information was helpful...
Have a nice day...

Here's something to try. In Device Manager, double-click the unknown device to open its properties. Click the Details tab. In the Property drop-down menu, choose Device Instance ID (or Device Instance Path for Windows Vista/7). You'll see a string of characters in the Value box.
In this string of characters, look for the letters VEN_. The numbers following this are the vender ID. Then look for the letters DEV_. The numbers following this are the device ID.
Go to the PCI Vendor and Device database here:
http://www.pcidatabase.com/
and enter the vendor and device ID for your search. This doesn't always find the right device, but it often does. After you figure out what the device is, you should be able to determine whether you can download the right drivers.

Hi

Thanks for using FixYa. I think you have stored more than 100 Caller ID messages and hence the caller ID is not showing on Uniden Tru8888. In the following cases the caller ID will not be shown-

If you answer a call before the Caller ID message is received (for example, before the second ring), the Caller ID message will not appear.

When the call is received via a telephone company that does not offer Caller ID service, the caller’s phone number and name does not appear. (This includes some international calls.)

When the call is via a private branch exchange (PBX), the caller's phone number and name may not appear.

You may receive any one of the following messages:

When a private name is received; Private Name
When a private number is received; Private Number
When a unknown name is received; Unknown Name
When a unknown number is received; Unknown Number
When invalid data is received; Incomplete Data

The Caller ID list stores information for incoming calls - even unanswered calls. You can store up to 100 Caller ID messages and phonebook entries (including Speed Dials) for each handset and the base. You can view the Caller ID list through the handset or base during a call or when the phone is in standby mode.

Memory locations for Caller ID messages and Phonebook entries (including Speed Dials) are common, you can store up to all 100 entries for each handset and the base. Caller ID messages are not stored when you have 100 phonebook entries. When you have stored a total of 100 phonebook entries and Caller ID messages, the oldest Caller ID message is overwritten.

Please do rate the solution and revert for further assistance.


Thanks

Try reinstalling the motherboard drivers, maybe something is wrong with the USB controller.

This indicates that the sound drivers are missing from your computer. You will have to identify the sound card that is installed on your computer before proceeding with downloading the correct driver. To identify the sound card, follow the steps below (Assuming that you are using Windows XP)

1. Open Device Manager (Right-click My Computer>Properties>Hardware>Device Manager)
2. The hardware whose drivers are missing will appear as Unknown device, so it’s easier to locate the device.
3. Right click on the unknown device and click on Properties.
4. Under the Properties window click on Details tab and select Device Instance Id from the drop down box.
5. You should see a code similar to this
   PCI\VEN_8086&DEV_27DC&SUBSYS_30868086&REV_01\4&1E46F438&0&40F0
6. The portion of the code highlighted in RED is the Vendor ID and the portion highlighted in GREEN is the Device ID. In this example:
   Vendor ID = 8086
   Device ID = 27DC
7. Once you have obtained both the IDs, proceed to www.pcidatabase.com . There you can either search for the vendor from the vendor ID or directly get information about the device along with the vendor name by searching with the device ID.

You should first check device manager for any issues with Network drivers.

Start--> Run --> devmgmt.msc

This command will launch "Device manager" window.

If you see a Yellow exclamation mark in device manager for NIC, follow the following steps to identify the card that is installed on your computer.

1. Open Device Manager (Right-click My Computer>Properties>Hardware>Device Manager)
2. The hardware whose drivers are missing will appear as Unknown device, so it’s easier to locate the device.
