Cisco AM10

Hello, I'm having a lot of trouble getting my Cisco AM10 Wireless-N USB adapter to work. First, I want to make sure usb_modeswitch is the right solution to my problem.

My wireless adapter is detected as a USB drive with lsusb -l:

From what I'm reading, I need to create a config file:

Code: Select all

########################################################
# Cisco AM10

DefaultVendor= 0x1307
DefaultProduct=0x1169

MessageEndpoint = 0x01

CheckSuccess=20

I got the MessageEndpoint and MessageContent from UsbSnoop, but I'm really confused as to which entry I should be getting the MessageContent from. I've seen a couple different TransferBufferMDL data values neither of which have worked:
55534243088019820002000080000a28000000000000000100000000000000

Running my config file gives me this:

Please let me know what I'm doing wrong. Thanks!

Did you sniff with the Windows driver already installed?

To me it looks like there is a lot of data exchange with the device in storage mode.

After you installed the "filter" in the sniffing program, clear any existing log ("Delete Log"), then start or resume log, then plug the device in (with driver already installed).

Note that with the driver installed, you probably won't see your original storage device as "Present" anymore because it will immediately be switched. Check the box "List Devices Not Present" to access it for filter installing.

teegee543 · Post by **teegee543** » 30 Mar 2011, 00:37

I did not have the Windows driver installed already. I installed the driver in XP and it was able to pick up wireless networks.

Here's the resulting log:
http://www.berrypi.com/UsbSnoop2.log

Here's another log that only had a filter on the Mass Storage Device. I'm not sure which device I should have had the filter installed on:

Post by **Josh** » 30 Mar 2011, 08:35

Hmm, your logs seem to start somewhere in the middle ...
Plug out your device, "Delete" the log, then start/resume logging, then plug in.

It is absolutely correct to install the filter only on the storage device; but make sure you get the right one - there might be annother one after switching which is usually a SD card slot.

So you want the original installation storage, with ID 1307:1169 (in Windows that would be "Vid_1307&Pid_1169"). This device ceases to exist at some point after the switching command, so the log should stop growing (hit "Refresh" to follow this).
This also means that the original installation storage is "not present" after switching; you have to find it in the long list.

teegee543 · Post by **teegee543** » 31 Mar 2011, 00:25

I've installed the filter on the original storage: ID 1307:1169, but Sniff USB won't let me resume logging when the device is unplugged. What am I doing wrong? I am using version Sniff USB 2.0.0006. Also, the mass storage device on the AM10 doesn't disappear when it gets switched. The wifi is enabled, but I can still access the USB drive in My Computer.

It looks like the drive has a hub built-in.

Post by **Josh** » 01 Apr 2011, 08:12

I do have that problem from time to time. I suspect one of the XP updates has meddled with the USB stack.

If you have deleted the log and "Resume" is greyed out, try to just plug in. Sometimes the logging starts right away.

teegee543 · Post by **teegee543** » 01 Apr 2011, 23:29

I managed to get logging to start right away, but I can only get that to work once per boot. Here's a log that hopefully starts at the beginning.

http://www.berrypi.com/UsbSnoop4.log

Thanks for the help so far!

Post by **Josh** » 02 Apr 2011, 09:51

Now the log does have a clear starting point. Very good.

Unfortunately, there are only standard storage commands in it, nothing outside of the norm ...

There is still the possibility that the switching command is issued through the hub device. Can you do it all over again with the filter installed on the hub ?
You can stop logging as soon as the network device is present - uncheck the "List Devices Not Present" before plugging in and hit "Refresh" repeatedly during logging, it should appear at some point.

The reason I think there's a hub involved is because of this lsusb listing:

But that device ID 1307:0169 never shows up in Sniff USB:
http://img856.imageshack.us/img856/4022 ... onal20.png

And nothing seems to ever get logged on the device in the screenshot with a filter installed (the second Cisco AM10). When the adapter gets switched, only the first Cisco AM10 device is "Present" and the Mass Storage device also remains "Present". The other USB devices you see on the list have nothing to do with the wireless adapter. They all are "Present" when I unplug the dongle:

That is all very mysterious ...

Could you do one last log with filters installed on all three Cisco devices?

Yeah, I'm confused as well... Sorry about the delay, here's a log with filters on all three Cisco devices:

Not bad.

It is now obvious that the modem device appears at millisecond 4562.

Before that moment there is a lot of "00" commands (... 06 00) which is basically an "idle" function like "are you still there?". This goes on for over 2.5 seconds. Then, right before the modem appearance, there is a "read" command. Maybe you can try that one - it would be unusual, but so is the whole device setup ...

That did not work. However, installing the driver in a Windows XP virtual machine and attaching the dongle to the VM somehow switches the device, allowing the wireless device to show up in lsusb:

Do you think we need to leave the mass storage device mounted for it to switch? When Windows XP does the switching, the dongle can still be seen as a USB drive.

Well, that would be a catch 22 - to send any custom command to a storage device, the storage driver has to be detached. Which means effectively unmounting the storage ...

Annother try:
Right before the repeating "idle" calls there is a sequence of "0xfd" commands (look for "0a fd"). This is not a standard SCSI or USB opcode. After these 11 commands there is only idling.

Here they are:

Phew. OK. Time for some copy-and-paste.

Since usb_modeswitch can only take three bulk commands so far, you could try to set up four different config files and run them in sequence. "NeedResponse" should be set to 1 in all of them. Skip everything else like SuccessCheck and add the -I parameter on the command line.

If you get into trouble, I will create a special mode for this device in a usb_modeswitch test version.

There is more. Two "WRITE" commands which are not quite in place.

Before testing them, make sure you can't write to the storage. Otherwise these are potentially dangerous.
