Question about JVC GR-D20EK Camcorder

3 Answers

Not recognised When I connect the camcorder (JVC-D20EK) to the PC by USB lead, the following message appears on the Desktop - USB NOT RECOGNISED. In Device Manager using the Driver tab, results in 'Unknown Device'. Clicking on this takes me to the Driver details tab. Driver Details tell me that "No drivers files are required or loaded for this device." Why not? What's going on? Sources tell me I may require a software disk which will contain the necessary drivers for the PC to see the Camcorder. Is this a fact? I have searched the JVC forums and elsewhere and find that everybody is floundering around looking for the same solution. The manufacturers are of NO help at all! The posted answers are completely useless! I am using Windows XP and a computer with enough spec to alter the orbit of a small planet. Can you assist me in this bemusing and seemingly insolvable problem - at least it is to a Silver Surfer? D F Richards

    The answer I have received has not helped so far!

    Have you any information as to the software disk

    I mentioned. Is such a disk necessary?

It is true that sometimes a hardware cannot be recognized by Windows and a manufacturer provided driver is required.

No driver can be found for your product, here's the XP compatibility list from JVC

Try connecting your camcorder to another USB port. Using one port all the time to connect and disconnect USB items a port can develop a range of files associated with configuring the USB connection. Some of these files might actually have been from your camcorder connected before, or some of these configurations could be from other USB items you connect to this port. Changing ports can often lead to an immediate good connection simply because there are no conflicting configuration files. If this does not solve your problem, we can now entertain the next process to try.

THIS IS A BIG ONE. This is the last thing to do. Before you try this process, please complete a full back up of your system. This is important as the next step can have side effects you did not entirely expect. AND Second, you might need your XP Install Disk (not in all cases). What this process is about is renewing all hardware/software configurations relating to USB connections.

Here is what you do:
1. Right click MY COMPUTER
2. Select PROPERTIES
3. Select HARDWARE
4. Select DEVICE MANAGER
5. Select UNIVERSAL SERIAL BUS CONTROLLERS
6. Right click on each USB CONTROLLER and select Uninstall
7. Uninstall all entries
8. Reboot your computer
9. As your computer re-boots it will reinstall all USB connections it detects
THEN, when all other USB items have been configured and connected by the system, you then should try connecting your USB camcorder

If these suggestions are implemented and you are still have connection difficulties with your computer, there are several other things to try. If you have another XP Computer you should try connecting your player to another computer to see if the problem is a player problem or not. If it still has this problem with the next computer, it maybe be a fault of the player.

IF YOU HAVE COMPLETED ALL the above mentioned and still have a problem, you should next contact the seller of this machine for further instructions of what to do next.

Try first unplugging computer power cord for five minutes, sometimes this solves the problem.

    The JVC-D20EK should be recognised automatically as an external disk, this will manage data on memory card only.

    If the Camcorder is not recognised, try unplugging power cord for ten minutes, or if it is a laptop unplug power and remove battery at same time.

    To transfer tapes you need to download generic JVC software.

    Here is the software download page for US/Canada.

    Check the user manual here go to page 33.

    It says USB is enabled nad software is available only for JVC D50/D40 only.

    No software had even been distibuted for D20, D20 does not connect through USB.

    For your model you need to use a PC with DV connector, not USB.

    The n use the PC video card software to capture files.

    That is the reason why nobody can get drivers.

You should have a DV Cable 4-pin to 4-pin firewire (part number VC-VDV204U ) which came with your camera. It would not have firewire on one end and usb on the other. They are two seperate technologies. see http://www.wisegeek.com/what-is-a-firewire-to-usb-adapter.htm
