Well , your Pen drive may be corrupted or virus infected.

I suggest to scan your Pen drive for virus.

If the problem will still be there just format your Pen drive.

I should solve your problem.

Vijay check your pen drive first with other PC (cybercafe) check the timing and then you will find one of the two things. either pen drive is down, or its PC. In case its pendrive have it formatted quickly. If it is your PC then have it defragmented. Also cleanup your disc space. Install download manager/accelerator. Run a registry cleaner utility and delete or get rid of any orphaned entries in that registry.

It must be problem with the system as the pen drive coying speed was double previously. It seems like your Hi-speed USB 2.0 drivers are corrupted. Your first step is to check that you have the latest USB 2.0 drivers on your system. Start by opening Windows Explorer and right-clicking on My Computer. Click the Hardware tab, followed by the Device Manager Button. Towards the bottom of the list you should see a heading 'Universal Serial Bus Controllers.' Click the small plus sign next to it. To see if you have USB 2.0, look for a line that says 'USB2 Enhanced Controller.' If you see the entry is missing or have yellow exclamation mark besides the entry, you can ensure the problem with the USB 2.0 driver.

If there is yellow exclamation mark besides the USB 2.0 driver entry, right-click and select 'Update driver' on that entry while your computer is connected to the Internet. If there is no entry basically means you have to install the USB 2.0 drivers. There are two steps you need to follow. Firstly you must ensure that you have installed Windows XP Service Pack 2. Get it from: http://www.softwarepatch.com/window s/xpsp2.html. download and install the Service Pack, then restart your system. Go back to the Device Manager - as shown in the first paragraph - and check the status of your USB controllers. If the USB2 Enhanced Controller has appeared without the yellow symbol, you should be ready to use USB 2.0. If not, you will need the specific USB 2.0 driver for your system. There are only six manufacturers of USB 2.0 controllers: Acer Labs, Intel, NEC, SiS, VIA and nVidia (which may appear as 'Standard Controller'), but sometimes they are re-branded by other companies. In this case, you will need to find out which Controller is on your system and visit the manufacturers site for an update or special instructions. Hope this would help.
