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 lack of USB modules for the kernel that boots?

@zeri could be! Which modules are required? Which package do they come in?

@root42 @zeri compare the output of `lsmod` from both kernels.

Capture `dmesg` too.

One or both (sets) should get you on the correct path.

@drscriptt @zeri yes, that’s my plan. Hope to find it’s just a module that’s missing.

@drscriptt So the output of lsmod is very similar on both. I installed an extra Intel sound driver, but that shouldn't interfere with USB, I think.

@root42 agreed
