Dotaz: usb xhci problem

[jap]

vazeni, mam usb2 zarizeni, ktere po pripojeni do usb2 portu vyhodi v dmesg error, tykajici se xhci, pravdepodobne jde o chybu pri komunikaci a usb2 hw nedokaze kominikovat, je to rozsirena chyba a reseni jsou ruzne uspesna, me by stacilo ukecat system, aby pro dane usb-id pouzil rovnou ahci

Mně tohle někdy dělá v jenom USB portu NTB, ostatní jsou v pohodě. Důvod neznám. Ale příčin výskytu asi bude víc, je to hodně častá chyba.

no xhci je usb3 a ahci je na SATA, takze asi mluvite o ehci

jestli nemate zadne usb3 zarizeni, tak jde xhci zakazat (podle distribuce, asi module blacklist) no a pak se bude pouzivat ehci, t.j. usb2
