Hello,

I have a usb ethernet adapter, available here:
http://www.dealextreme.com/details.dx/sku.2797

This adapter works perfectly on my x86 ubuntu linux system, but I
cannot get it to work on the beagle board.

When I plug the ethernet adaptor into my x86 system, dmesg reads:
usb 2-2: new full speed USB device using uhci_hcd and address 20
usb 2-2: configuration #1 chosen from 1 choice
eth1: register 'dm9601' at usb-0000:07:00.0-2, Davicom DM9601 USB
Ethernet, 00:60:78:05:e9:c9

ADDRCONF(NETDEV_UP): eth1: link is not ready
ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready
eth1: link up, 100Mbps, full-duplex, lpa 0x41E1

On the beagle board:
usb 2-1.4: new full speed USB device using musb_hdrc and address 46
usb 2-1.4: device v0a46 p9601 is not supported
usb 2-1.4: configuration #1 chosen from 1 choice
eth0: register 'dm9601' at usb-musb_hdrc-1.4, Davicom DM9601 USB

usb 2-1.4: USB disconnect, address 46
eth0: unregister 'dm9601' usb-musb_hdrc-1.4, Davicom DM9601 USB Ethernet

Am I missing a kernel module? The module dm9601 is loaded. Maybe
someone has some insight?

I also have two usb wifi adapters which work perfectly on my x86
ubuntu system and neither work on the beagle board. I have some
devices which are virtual comm ports also over usb, and they work on
the beagle board.. but I have noticed glitches like the device having
"input/output errors" and required me to unplug and plug the device
back in which I have never seen before.

When I run the usb port in device mode, I can connect to my other
computer via usb ethernet and this works without problems.. but this
is different from host mode.

I am using the 2.6.28 kernel and modules from:
http://www.angstrom-distribution.org/demo/beagleboard/

Sorry if I left out any details, please ask. I would like to
understand the problem.

Thanks,
Sean

Do you have a powered hub in the middle? The otg port only provides 100mA.

Hi,

I have managed to get an external harddrive, and bluetooth working
through my powered hub, so that is not the issue. I am not sure why
my networking usb devices (wifi and ethernet) do not work.. both work
fine on x86 linux.

The wifi adapters complain about not finding the firmware. It is the
zd1211 driver.. so it really should work, for example in dmesg:

usb 2-1.2: Could not load firmware file zd1211/zd1211b_uphr. Error number -2
WARNING: at drivers/usb/musb/musb_host.c:128 musb_h_tx_flush_fifo+0x94/0xd4()
Could not flush host TX0 fifo: csr: 020a

If anyone has seen these errors or can make sense of them I would like
to know. Happened with 2.6.28 and 2.6.29 kernels.

If someone has a working zd1211 usb wifi adapter with their beagle
board, I would like to ship you mine so you can try it with your
beagle and see if it works or not. Then maybe we can determine more
accurately the source of the problem and fix it.. I am sure there are
bugs in musb.

Thanks,
Sean

the zd1211 firmware is not in the angstrom image (assuming you used
that one).
See http://www.elinux.org/BeagleBoard/James#Adding_WiFi_support on how
to get it.
zd1211 works fine for me!

Hi,

FM, I tried with the instructions from the link you sent without success.

I have tried copying the firmware files from my ubuntu box (as I found
soneone on this mailing list had one with success last october) onto
the sd card, and also downloading the firmware from sourceforge. I
get the same result:

usb 2-1.2: new high speed USB device using musb_hdrc and address 3

ADDRCONF(NETDEV_UP): wlan0: link is not ready

If I remove the firmware files entirely I get:

usb 2-1.2: new high speed USB device using musb_hdrc and address 4

usb 2-1.2: Could not load firmware file zd1211/zd1211b_ub. Error number -2
zd1211rw 2-1.2:1.0: couldn't load firmware. Error number -2

It looks like it can get the zd1211b_ub, but not zd1211b_uphr, but I
confirmed I do have both files in /lib/firmware/zd1211

Any insight is appreciated.

Thanks,
Sean

I get a mixture of Error number -2 and Error number -110 with my
Trendnet usb wifi adapter using the zd1211 driver. If anyone ever
figures out how these problems, I'd be very interested to know. I'd
suggest trying the old 2.6.26 kernel and see if that works. Once upon
a time it worked for me on that kernel.

Error 2 is ENOENT = no such file or directory
Could it be that the name is wrong? Or that the filemode is wrong?

My files are all mode 644 (rw-r--r--)
md5sums of my fw files (from my opensuse box, seems I reinstalled my
beagle and not restore the files)

Hi,

Error 2 is ENOENT = no such file or directory
Could it be that the name is wrong? Or that the filemode is wrong?

My files are all mode 644 (rw-r--r--)

All of the files are 644 -rw-r--r--

Does this look right:

root@beagleboard:/lib/firmware/zd1211# ls -l
-rw-r--r-- 1 root root 4018 Mar 19 2009 zd1211_ub
-rw-r--r-- 1 root root 5120 Mar 19 2009 zd1211_uph
-rw-r--r-- 1 root root 5120 Mar 19 2009 zd1211_uphm
-rw-r--r-- 1 root root 5120 Mar 19 2009 zd1211_uphr
-rw-r--r-- 1 root root 3584 Mar 19 2009 zd1211_ur
-rw-r--r-- 1 root root 4018 Mar 19 2009 zd1211b_ub
-rw-r--r-- 1 root root 5120 Mar 19 2009 zd1211b_uph
-rw-r--r-- 1 root root 5120 Mar 19 2009 zd1211b_uphm
-rw-r--r-- 1 root root 5120 Mar 19 2009 zd1211b_uphr
-rw-r--r-- 1 root root 3584 Mar 19 2009 zd1211b_ur

I have completely different checksums than you do
for the files. I think from my errors the kernel finds zd1211b_ub but
not zd1211b_uphr is this right?

What kind of dongle do you have?

from lsusb -v:

  idVendor 0x0ace ZyDAS
  idProduct 0x1215 WLA-54L WiFi
  bcdDevice 48.10
  iManufacturer 16 ZyDAS

Thanks for the help so far.

Interesting.
My file sizes are the same as yours. I've been lazy with the md5sums
as I just took them from my opensuse system.
However I had an interesting :frowning: surprise.
Whereas my dongle worked with 2.6.27, it does not work any more with
2.6.28 (r15)
error: usb 1-2.1: Could not load firmware file zd1211/zd1211_uphr.
Error number -2

puzzled !

Wow.. I have only used 2.6.28 and 2.6.29. I tried 2.6.27, and yes now
the wifi works! So it looks like now I need to do some diffs and try
to figure out what changed dealing with firmware so I can fix the
newer kernels.

Have you seen this error?

DMA misaligned error with device 0

Good luck. I hope you figure it out as it will benefit me and others
too!!!

I'm not sure I saw that error. Where exactly does it occur?
A comparison is probably the best way forward (or a git bisect)
Note that .28 also brought me problems with SDHC cards (see other
post) although others do not seem to have that problem.
Looking forward to your results (you might also want to report them in
the linux-omap mailing list).

Btw: where do you get your kernel from? I'm using angstrom kernels.
I've been looking for a .29 kernel; although it is in oe there are no
patches so I never tried to build and test it

Hi,

I am pulling directly from this:
git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6.git

or for dss2 from:
http://www.bat.org/~tomba/git/linux-omap-dss.git

I was going to do a git-bisect in the firmware directory.. but I had
trouble compiling 2.6.27 from the dss2 tree.. I'm trying with the old
dss. Everything takes a long time on my slow machine. I can checkout
compile and test about 8 kernels a day.
