 |
|
when i connect usb 2.0 devices to my box, they use UHCI (usb 1) instead of EHCI (usb 2). i have the correct modules loaded, hotplug is loaded as well. my mobo is a asus p4c800, in the bios i choose high-speed (480mbps). with this setting, usbview does not show the EHCI controller, but, if i choose full-speed (12mbps) the EHCI controller is listed.
how can i do to have my usb2 devices working properly? thanks, michele |

what does /var/log/messages say when you plug in a device?
(eg "new high speed USB device using address ...")
What does
gzcat /proc/kernel.gz | grep HCI
say?
What does
lsmod | grep hci
say after you put in a device?
What does
grep -i usb /proc/pci
say?
What does
modprobe uhci_hcd
say (if anything)?
modprobe ehci_hcd
?
Moo. |
