Currently Im facing an issue when Im trying to connect any usb flash drive to my pc.

ok, below is what happens to me:

1) I can connect usb keyboard and mouse without any issue.

2) however when i connect usb flash drive, there are 2 situations that are occuring randomly

a) there is no usb drive mount in my computer, when device manager is checked, it shows
error code 10, but is shown in disk management.

b) my computer will have usb drive mounted, but when I click on it, it is empty. on right click the properties, the disk space show 0. (there are files within the usb)

what i have done is:

1) run CCleaner to repair the registry, restart and try, but still not working.

2) uninstall the drive in device manager, restart and try, but still not working.

3) tried the port that connects mouse and keyboard, but does not work.

anyone who experienced these problems before please guide me.

any suggestions or solutions would be greatly appreciated.

Thanks,

Tony
