Right, it looks like I didn't read carefully my logs. :)

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.

This is what I get when loading the libertas module with libertas_debug set
to 255:

[421350.471415] usb8xxx leave: if_usb_init_module():1036, ret 0

So I would exclude that an USB problem is going on. Plus, if I load both
modules without any firmware being available, usb8xxx tells me that
request_firmware() failed:
[421274.018749] usb8xxx enter: if_usb_init_module():1028
