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*:

@zeri could be! Which modules are required? Which package do they come in?
@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.
-
@mbpaz maybe…? Would that influence lsusb not showing the attached devices?
-
@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 @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.

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??
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...

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...

> sudo lspci -s 07:00.0 -k -v
