I uninstalled the driver from my transcen jf v30 4gb pendrive. Now windows says hardware not recognized.


Hi s8vysakh6 ,

I would suggest you to try the following steps:

Step 1: Run the fixit provided in the link below.
http://windows.microsoft.com/en-US/windows-vista/Tips-for-solving-problems-with-USB-devices
Check if the issue is resolved

Step 2: Connect the device to a different USB port\ and also connect the USB pen drive to another computer to eliminate issues with the pen drive itself.

If the issue persists,

Step 3: Reinstall USB controllers.


First, please disconnect all USB devices and then perform the following steps:

1. Click "Start", type in Device Manager the Search bar and press "Enter". Click Continue if necessary.

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

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

Then, restart your computer and Windows vista will reinstall all USB controllers automatically.

Step 4: Update the motherboard driver to the latest version.
Note: Please check with the motherboard manufacturer before installing the driver.

If the issue persists, you may want to check with USB pen manufacturer for any unknown issues.

Hope this will help !

Unknown device


Hello,
Plug it through different USB ports, even a USB Hub, or on a different computer. Sometimes rebooting solves the problem. I suspect it is a USB problem, especially on laptops with a small number of USB ports.
I have given mine up as dead several times, but it always comes back up gain.
Hope it helps.

Transcend connection


For all of you who are unable to make USB drives work or still are getting the “USB Device not recognized”, try this method.

Download usbstor.inf and usbstor.pnf files (links are below) and copy them to

C:\ windows\inf  folder.

(click yes to overwrite the files if windows asks)

Remove the Unknown device from the Device Manager - Other Devices.

Inserted the USB drive and lo and behold! It should be recognized in a jify!


usbstor.inf and usbstor.pnf can be downloaded from here:

http://www.infdump.com/download-inf-files_new.php/inffiles/U/USBSTOR.INF/5.1.2600.0/download.html

http://www.pnfdump.com/download-pnf-files.php/pnffiles/U/usbstor.PNF/download.html


Hope this helps for everyone whose USB drives are still not recognized.
