windows 7 - Machine doesn't recognize some USB flash drives
2014-07
My friend's Windows 7 x64 ultimate machine recognizes some USB flash drives but not some other ones. The types of all are USB2 and also all drivers are installed (device manager). I don't know what is the problem. I also have done the works of here: http://www.techspot.com/community/topics/my-machine-doesnt-recognize-some-usb-flash-drives.202702/#post-1404832
And this is an image from that flash drive (silicon-Power 4g). Any idea how to solve he problem please?
On a machine, I dual-boot Windows XP and Windows 7 (both 32-bit).
Several external hard drives work well under Windows XP, but under Windows 7 none of them is shown as a drive in Explorer.
The only thing that happens under Windows 7 is: after plugging in the USB cable, the system recognizes a plugged device and shows the "safely remove hardware" toolbar-icon (which refers to some Bridge device).
What can be the reason?
What additional information could I provide to clarify the problem?
right click on Computer > Manage > Disk Management
if the drive is showing there, assgin a drive letter.
