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

@root42 Does it work with Windows or macOS without needing special drivers?

@dr_laemmerbein Yes, it works fine in macOS as mass storage. No issue. However I just noticed that no other USB mass storage gets detected either. This is on the 2017 13" MacBook Pro. I have tried a USB thumb drive (That I installed Mint off of!) and a card reader with an SD card. No dice. Something is seriously wrong.

@root42 Did you install a kernel update by any chance? Then you might need a reboot to make it work again, I ran into that a few times...

@dr_laemmerbein lots of reboots...

@root42 Maybe you can get some hints by running `dmesg -w` in a terminal as root. This will show you all the kernel events and if you plug in your USB drive you should see some logs related to that. Maybe you'll get an error message or something like that.

@dr_laemmerbein I am doing that. No logs when plugging in USB 3 devices. Zip. Zilch. Nada. That’s the weird thing.
