USB ports malfunction

Using a different USB port might solve the problem, turn the phone off completely and plug the phone in after doing so turn the phone on if the same problem persists then contact the phone manufacturer and ask if its a common fault

plug the hard drive into a different usb port, or take it to a friends computer and try it there, if it works the problem is in your usb ports, these issues are hard to solve, but first make sure the drive is actually ok

This happens when anything draws over 500mA, of current, if it was working OK, before, and is working now but displays that message, or not working, well in any case it seems to have gone faulty, and somehow, is now drawing more current drain, the USB port can supply. It may have been spiked too.from all the plug/unplug especially if the safely remove hardware is not used.

Try changing the USB cable that connects the hard disk to the computer, this message usually comes when the cable is damaged.

please format your pendrive or anything esle you connect through usb port.

you need to reinstall printer driver .
"USB NOT RECOGNIZED" error come when windows cant to find driver of a new device .

When you connect a hard drive and any other USB device to a 4 port hub you have to use the external power supply all the time. You may have fried the power pins on the USB port you used to connect the 4 port hub. If you can get the hard drive to work separately on the USB port, the 4 port hub may no longer be passing power from the laptop.

Hello ak1979 ...

1. You're plugging in your Transend USB flash drive to your computer's USB port (as you've done many times successfully before with this SAME flash drive)?

2. It says "windows not recognise usb drive due to malfunction"?
a. Is that EXECTLY what the error says?
b. Is "it" an error dialog (window that pops up), or an error message from your Windows Event error logs? If a dialog, are there any pertinent error message entries in your Windows Event (System) log [Start > Run > type "eventvwr.msc" (without quotes), then "OK"]?

Try a bit of deductive troubleshooting:

1. Restart (Reboot) your system [for a fresh start, if you will].
2. Try plugging in your USB flash drive again, but in a DIFFERENT USB port.
3. Try plugging in ANY OTHER "known good" USB device into the same USB port(s) used thus far that failed.

NOTE: If you EVER get any indication Windows recognizes the flash drive (like no error msg, or it shows in "My Computer"), IMMEDIATELY perform a "Check Disk" on it:

1. Start > Run... > type "cmd" (without quotes), then "OK".
2. Type "chkdsk DRIVE_LTR: /f" (without quotes), then hit "Enter" [where DRIVE_LTR is the drive letter of your USB drive]. EXAMPLE: chkdsk E: /f

Good luck, and please post back:

• to provide any corrections/updates/clarifications.
• if you have any further questions.
• to let me know how things work out.
