			Years ago I recall davidfor posting a link to a USB explorer tool that would help clean some of the junk out of installed / partially installed USB drivers on your system. I'll try searching for that later when I'm on a PC Sent from my Pixel 7a using Tapatalk |

			For what it may be worth, I think the issue is the software from Challenger Backup Solutions that you have installed and which seems to have attached itself as the driver for your Kobos. For my setup, Microsoft is shown as the driver provider. Perhaps removing the Challenger Backup Solutions driver might help. You might also want to check A very strange USB problem. (the link is to page 3 of the discussion). Last edited by DNSB; 05-15-2024 at 01:10 PM. |

			Ran across this item during a search for a driver for an old USB camera: USB drive showing as Local Disk on Windows 10 Same Challenger Software driver and apparently removing it from Control Panel => Programs and Features worked for the poster. |

			You can try the removal of the Challenger Backup driver from Programs and Features. Alternatively, you can open it in Device Manager and select Show hidden devices from the View menu. Look under Disk drives, select a Linux File-Stor Gadget USB Device, open it's properties and select Uninstall Device. In the confirmation dialog, if you see Delete the driver software for this device, select that and continue. You may need to uninstall all USB devices using the Challenger Backup driver before you will get the uninstall driver option. Quote:

 MS doesn't give personal support to end users. Likely it's something inadvertently installed as Win 11 is between 25% and 28% of Windows users now. It was a slightly ironic comment. | |

			Depending on how comfortable you feel with this, one other way to remove the driver would be to open USBDeview. Select a Linux File-Stor Gadget device, right click on it and select Open INF file. In the editor window, if the inf file name does not show as usbstor.inf, copy the filename. Still in USBDeview, uninstall any instances of mass storage devices. Open the Windows directory and do a search for that filename. Rename any instances to filename.inf.dnu. Reboot your computer. To download USBDeview, see USB Deview on Nirsoft's site. The download link for the 64 bit version is https://www.nirsoft.net/utils/usbdeview-x64.zip |
