Cześć,

Mam problem, moje porty USB działają w trybie USB 1.1.... Jak to zmienić?

Najpierw sprawdź czy czasem to nie są porty usb 1.1 lub czy urządzenie czasem nie jest 'full speed'. Mnie też się wiele wydawało

spójrz

W moim wypadku (nie wiem czy to ma zastosowanie u innych)

[    1.796296] usb usb1: Manufacturer: Linux 2.6.26-1-amd64 ohci_hcd

oznacza, że Linuks wykrył koncentrator FullSpeed (usb 1.1, 12 Mbps), znowu

[    1.912273] usb usb2: Manufacturer: Linux 2.6.26-1-amd64 ehci_hcd

oznacza, że mam hub'a HighSpeed (usb 2.0, 480 Mbps)
Upewnij jakie porty należą do jakiego koncentratora (skonsultuj się nawet z dokumentacją do płyty głównej), potem wydaj polecenie

 dmesg |grep usb
