Would that be:
|__ Port 2: Dev 2, If 0, Class=Mass Storage, Driver=usb-storage, 12M
There is no disk of 12M connected. There is one of 2TB, and another of 1TB. The only other USB port is empty. If it refers to the card reader, there is no card.
I did "rmmod uhci_hcd" and the messages stopped.
Now there is time to think without filling the logs.
I'd say, something is fishy with that card-reader. After the driver removal, is it still working? Be aware, some older hid's (mouse, keyboard) get funky without uhci_hcd / ohci_hcd driver, most work fine with ehci_hcd (USB 2) hosts. Hint: that "12M" refers to the speed of the usb connection. "10000M" is USB 3.1 max (9.7 GBit/s also "super-speed") "5000M" is USB 3.0 max (4 Gbit/s, named "super-speed") "480M" is USB 2.0 max (named "hi-speed") "12M" is USB 1.0 max (named "full-speed") "1.5M" is named "low-speed" Drivers: Offical Name (Manufacturer) kernel driver ========================================= USB 1.0 + USB 1.1 UHCI (Intel, VIA) uhci_hcd OHCI (others) ohci_hcd USB 2.0 EHCI (all) ehci_hcd USB 3.0 + 3.1 xHCI (all) xhci_hcd see: [en] https://en.wikipedia.org/wiki/USB [es] https://es.wikipedia.org/wiki/Universal_Serial_Bus - Yamaban. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
