I tried these ones, 4d80059fe935edef77c0745a426f6aab usb8388.bin.olpc 9854fff247b970cc34fd14785384ffeb usb8388.bin.rh (I found both URLs in some Fedora installation script), but I still get the same error message. > If probing fails and udev doesn't even load usb8xxx.ko, then you > have an USB problem and the wireless mailing list might not be > of much help to you. This is what I get when loading the libertas module with libertas_debug set to 255: [421322.049447] usb8xxx enter: if_usb_exit_module():1044 [421322.049502] usbcore: deregistering interface driver usb8xxx [421322.049717] usb8xxx leave: if_usb_exit_module():1054 [421323.407779] libertas enter: libertas_exit_module():1527 [421323.407878] libertas leave: libertas_exit_module():1531 [421327.355499] libertas enter: libertas_init_module():1519 [421327.355618] libertas leave: libertas_init_module():1521 [421330.901950] usb8xxx enter: if_usb_init_module():1028 [421336.502698] usb8xxx: URB in failure status: -71 [421336.622483] usb 1-4: reset high speed USB device using ehci_hcd and address 6 [421337.992174] usb 1-4: reset high speed USB device using ehci_hcd and address 6 [421339.361828] usb 1-4: reset high speed USB device using ehci_hcd and address 6 [421340.731494] usb 1-4: reset high speed USB device using ehci_hcd and address 6 [421342.101171] usb 1-4: reset high speed USB device using ehci_hcd and address 6 [421343.470845] usb 1-4: reset high speed USB device using ehci_hcd and address 6 [421344.840515] usb 1-4: reset high speed USB device using ehci_hcd and address 6 [421346.210185] usb 1-4: reset high speed USB device using ehci_hcd and address 6 [421347.579869] usb 1-4: reset high speed USB device using ehci_hcd and address 6 [421348.949530] usb 1-4: reset high speed USB device using ehci_hcd and address 6 [421350.319203] usb 1-4: reset high speed USB device using ehci_hcd and address 6 [421350.471152] usb8xxx: probe of 1-4:1.0 failed with error -12 [421350.471354] usbcore: registered new interface driver usb8xxx [421350.471415] usb8xxx leave: if_usb_init_module():1036, ret 0 So I would exclude that an USB problem is going on.
