USB taking too long to transfer vista


Note that USB ports (in your computer) and USB devices can either be "USB 1" or "USB 2" speeds.

While "USB 2" to "USB 2" connections are up to 480 Mbits/second,
any "USB 1" to "USB 2", or "USB 1" to "USB 1", connections,
will max-out at only 11 Mbits/second.

So, check that you have a "USB 2" device.
then check that you are connecting to a "USB 2" port on your computer.

Give more details about your computer, and your USB device.

Unable to access my 4 GB Transcend pen drive with Windows Vista Home Premium Edition. Able to access it with Windows XP successfully but always prompting "Unable t find driver" when tried with Vista


Here are the 3 possible solutions to this problem,

SOLUTION 1 :- 
Make sure the you have the Service Pack 1 installed for you vista computer.
You can find it out by opening the run command and type "winver" (without quotes) there. If it's not showing SP1 please update Windows Vista to Service Pack 1 which includes the update to fix this problem as this was the problem when vista was launched but fixed with SP1.

If updating vista does not resolve the issue try the solution provided below:

SOLUTION 2 :- 

Manually locate the driver within the Vista operating system. 

Microsoft Windows Vista may not find any driver for the device that is plugged in the USB port because the usbstor.inf (for MSC device) or wpdmtp.inf (for MTP enabled devices) is not present inside the C:\Windows\INF folder.  

To resolve this issue, you must copy the driver files to the C:\Windows\INF folder. 

Browse to the following folder:

1. C:\Windows\System32\DriverStore\FileRepository. 
2. Look for the folder that starts with usbstor.inf_. 
3. Copy all the files inside this folder to C:\Windows\INF. 
4. Disconnect and reconnect the device.

2. Type regedit on the start search field, then press Enter.

5. Click View, then select Show hidden devices.

  exit

1. Click Start
