I have a Smartbuy 16Gb USB 2.0 flash drive (whith new memory controler) that is not recognized in any Linux system, but on Windows it recognized and worked fine.

When I connect it to the PC on Linux system, nothing happens. In dmesg appears this lines:

[ 2454.940289] usb 2-1.3: new high-speed USB device number 9 using ehci-pci
[ 2455.051632] usb 2-1.3: New USB device found, idVendor=13fe, idProduct=4300

[ 2457.252279] usb 2-1.3: reset high-speed USB device number 9 using ehci-pci

In lsusb:

Bus 002 Device 007: ID 13fe:4300 Kingston Technology Company Inc. 

fdisk -l and parted -l not return recognizing the USB device or partitions.

This solution: https://superuser.com/a/1107319 and reformat on Windows to fat32, didn't work.

    Have you tried a different USB port such as one that's using USB 2.0? – Nasir Riley Mar 14 at 2:21

    Yes, I was tried on different ports, 2.0 and 3.0. I connect to dicrect ports from back-side panel of the system motherboard. Other USB flash drives, and devices working fine. – Wnsemn - Mar 14 at 6:12
  • The four resets are looking suspicious, what you should see instead are an attempt to read the partition table, and at least an assignment to /dev/sdX if no partition table is found. Any trouble with other USB devices under Linux? If you have a powered USB hub, can you connect it, and connect the flash drive to the hub? What kernel are you using, and can you upgrade to a newer kernel (to rule out driver trouble)? – dirkt Mar 14 at 8:39
  • 1. Assignment to /dev/sdX not happening. This is realy last strings of dmesg after plug USB drive. 2. I have no trouble with any other USB devices under all systems. 3. > If you have a powered USB hub, can you connect it, and connect the flash drive to the hub? Now I don't have USB hub, but this is a very strange advice. I have no problems with system power. In most cases, it is advised not to use USB hub if happen any problems. – Wnsemn - Mar 14 at 12:25
  • 4. Current kernel of my system Kubuntu 18.04 is 4.15.0-46-generic. Also I tried in systems from Ubuntu 12.04 to 19.04, and Fedora 29. But USB drive was not work, and output of dmesg was same. – Wnsemn - Mar 14 at 12:25

  • To access the USB drive first you need to mount it.
  • After you plug in your USB device to your USB port, Linux system adds a new block device into /dev/.
  • Use command sudo fdisk -l
  • This command will list all the detected devices, check out your USB by checking the storage of the list shown.
  • Note the block name of the USB drive (something similar - /dev/sdc, can change depends on your system).
  • mount it using mount /dev/sdc /mount/point/
  • I'm not new Linux user. Of course I know those things that you wrote. I can't mount it because block device of flash drive is missing in the system. – Wnsemn - Mar 14 at 0:42
