[BUG] libertas: probing for Marvell USB8388 fails

[Stefano Brivio]

Marvell USB8388, running on wireless-2.6. Firmware is:
421964206b0699014a11256ac48dd0a8  /lib/firmware/usb8388.bin

Loading the usb8xxx module, I get:

lsusb says "Bus 001 Device 003: ID 1286:2001". And when I insert 
the card, I see

usb 1-1: new high speed USB device using ehci_hcd and address 3
usb 1-1: configuration #1 chosen from 1 choice

When I modprobes usb8xxx.ko (I have it in my module blacklist), I 
get an additional two lines:

libertas: eth1: Marvell WLAN 802.11 adapter
usbcore: registered new interface driver usb8xxx

After this, the USB stick works.



I use this firmware:

$ md5sum /lib/firmware/usb8388.bin
f1dfa0042efd61dc138b01fdf8c0cdab  /lib/firmware/usb8388.bin

As I got this firmware some months ago (and I hardly use this 
device), I cannot say which download link I've used.

Same here:

As long as probing fails, I doubt that my issue is firmware related...

Any clues about how to debug this further?

I was not sure that probing failed for you. I saw an URB submit 
error.

If usb8xxx.ko and libertas.ko get loaded, then it might be a 
wrong firmware. When the USB driver loads, it first uses URBs to 
send a helper firmware to the card. Then this helper firmware 
get's started. And then it sends again URBs to the card, e.g. 
for setup stuff. Now if the helper firmware is bogus and doesn't 
accept the URBs to download the real firmware ...


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.

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:

Try a later firmware from:

http://dev.laptop.org/pub/firmware/libertas/

Is this a usb8388 dev board you got from OLPC?

I tried these ones, it still doesn't work.

Which branch of wireless-2.6 are you running?  What kernel version?

I can't find this.

That is indeed the latest SHA for #everything. Anyway the SHA on each
commit changes upon rebase. It seems this is what happened. You're
probably better off checking based on date. I believe Stefano's issues
are the same ones as the one I reported. Would it have to do with the
old bcdVersion? Does the device need its firmware upgraded first? If
so how do we do this?

I tried this last week with the wireless-2.6/everything libertas bits on
2.6.22 and it worked fine there, with the latest firmware from
laptop.org.  Is your bcdDevice 3006 you said?  You may need to flash the
Boot2 firmware.
