Hi all, I thought I had read that USB 2.0 was required for the USB FOB, but I cannot fine it anywhere in the documentation. Both systems I have showed that the FOB is running at 12 MHz. Should this be running at 480 MHz? # ./usbtree.pl /: Bus 04.Port 1: Dev 1, Class=root_hub, Drv=uhci_hcd/2p, 12M /: Bus 03.Port 1: Dev 1, Class=root_hub, Drv=ohci_hcd/2p, 12M |_ Port 2: Dev 2, If 0, Prod=C-Media USB Headphone Set, Class=audio, Drv=snd-usb-audio, 12M |_ Port 2: Dev 2, If 1, Prod=, Class=audio, Drv=snd-usb-audio, 12M |_ Port 2: Dev 2, If 2, Prod=, Class=audio, Drv=snd-usb-audio, 12M |_ Port 2: Dev 2, If 3, Prod=, Class=HID, Drv=usbfs, 12M /: Bus 02.Port 1: Dev 1, Class=root_hub, Drv=ohci_hcd/3p, 12M /: Bus 01.Port 1: Dev 1, Class=root_hub, Drv=ehci_hcd/5p, 480M |_ Port 2: Dev 2, If 0, Prod=USB DISK 2.0, Class=stor., Drv=usb-storage, 480M I connected a storage device just to prove that the EHCI was functioning.
