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*:

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?

@root42 some udev rule in the installed version?

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

@mbpaz maybe…? Would that influence lsusb not showing the attached devices?

@root42 don't know. But that's something it is probably safe to ask a chatbot ... worst case you load a module you don't need. Might also be that there are no modules because a kernel update failed.

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

@cheesefox I have to look that up. My active desktop Linux times have been 15 years ago. Quite a bit has changed since then.
-

@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.

So my current working hypothesis is: Live Linux Mint uses kernel 6.14, my installation uses kernel 6.17. This is probably what causes the regression?
So I might want to downgrade the kernel...

#linux #linuxmintNope, that was not it. I downgraded to Linux 6.14.0-37, but USB still doesn't work. So it must be something with my installation! But what?

@root42 I still have some problemas mounting usb from friends in Ubuntu Focal. Can you believe that?
May it be a permissions issue? -

I am onto something: Attaching an OLD Apple keyboard with a USB-C to A adapter WORKS. But all my USB3.x devices do NOT work!
So how do I tell the USB controller to also work with USB3 devices...? Which works on the live thumbdrive!

@root42 it sounds like it does not load some usb drivers. But for default usb never seen that happen.

@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...

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 I also had this problem once where the kernel showed the usb drive was plugged in but no /dev/sd* showed up, the problem was the usb kernel modules weren't loaded so 'modeprobe usb' or a similar modeprobe command to that fixed it

@root42 Is your USB controller properly listed in `lspci`? And if it is, what kernel options does it use (see with `lspci -s <address of controller> -k`. For example, here's mine:
04:00.3 USB controller: Advanced Micro Devices, Inc. [AMD] Renoir/Cezanne USB 3.1
Subsystem: Advanced Micro Devices, Inc. [AMD] Renoir/Cezanne USB 3.1
Kernel driver in use: xhci_hcd
Kernel modules: xhci_pci -

@dr_laemmerbein lots of reboots...
