I have an issue with mounting a cheap smart watch in #linux: Device is seen by the kernel, but never registered as a storage device /dev/sd*:

usb 1-2: new full-speed USB device number 3 using xhci_hcd
usb 1-2: New USB device found, idVendor=0e8d, idProduct=0002, bcdDevice= 1.00
...
usb-storage 1-2:1.0: USB Mass Storage device detected
scsi host0: usb-storage 1-2:1.0

Ok, the plot thickens. When booting from the Linux Mint USB stick, the USB ports work. But when booting the installed version, USB ports are broken. Why??
@root42 some udev rule in the installed version?
@mbpaz maybe…? Would that influence lsusb not showing the attached devices?
@root42 @mbpaz potentially if usb_modeswitch is involved
@cheesefox I have to look that up. My active desktop Linux times have been 15 years ago. Quite a bit has changed since then.
