I have problem with my pendrive, I need data which are on it, but...:

  1. lsusb (after a few min it wouldn't see it again):

    Bus 002 Device 023: ID 0951:1642 Kingston Technology DT101 G2

  2. dmesg | grep sd -> didnt see it, so I used only dmesg:

According to the dmesg excerpt, the disappearance of the device in the lsusb listing, and the driver issues Windows reports, your USB drive is terminally broken. A good data recovery tech may be able to salvage the data on it, since often only the USB interface chip is broken, not the flash memory or its controller.
