Description Chris Morgan 2005-11-02 18:12:38 UTC
Most recent kernel where this bug did not occur: 2.6.14 compiled with gcc 4.0.2
Distribution: debian(hand built 2.6.14 kernel though)
Hardware Environment: amd64 3500+ cpu, 1gb ram, not overclocked
Software Environment: debian unstable
Problem Description:

Loaded up usbserial and ipaq driver with vendor=0x413c product=0x4011.  dmesg
shows the pda being found and ttyUSB0 and ttyUSB1 created.

I run these commands as root to establish a connection through the character device:

synce-serial-config ttyUSB0
synce-serial-start

and after running 'synce-serial-start' get this oops:

ipaq 2-1.4:1.1: device disconnected
usb 2-1.4: new full speed USB device using ehci_hcd and address 4
ipaq 2-1.4:1.0: PocketPC PDA converter detected

ipaq 2-1.4:1.1: PocketPC PDA converter detected

I get this oops under 2.6.12, likely tainted by loading the nvidia driver:

Comment 1 David Eriksson 2005-11-03 00:21:07 UTC
The SynCE project has received a number of reports about crashes with the "ipaq"
driver and Windows Mobile 2005 devices. The Dell Axim X51v is such a device.

Contrary to all devices known to work with the "ipaq" driver, these have
bDeviceClass, bDeviceSubClass and bDeviceProtocol set as in the
/proc/bus/usb/devices output below:

T:  Bus=02 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#=  9 Spd=12  MxCh= 0
D:  Ver= 2.00 Cls=ef(unk. ) Sub=01 Prot=01 MxPS=16 #Cfgs=  1
P:  Vendor=0bb4 ProdID=0b01 Rev= 0.00
S:  Manufacturer=MSFT
S:  Product=PocketPC USB Sync
C:* #Ifs= 2 Cfg#= 1 Atr=c0 MxPwr=500mA
I:  If#= 0 Alt= 0 #EPs= 1 Cls=ef(unk. ) Sub=01 Prot=01 Driver=(none)
E:  Ad=81(I) Atr=03(Int.) MxPS=   8 Ivl=1ms
I:  If#= 1 Alt= 0 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00 Driver=(none)
E:  Ad=82(I) Atr=02(Bulk) MxPS=  64 Ivl=0ms
E:  Ad=03(O) Atr=02(Bulk) MxPS=  64 Ivl=0ms

If the "ipaq" driver is loaded with the vendor/product identifier above,
and the device is connected, the module crashes.

There is a bug in the SynCE bug tracker for this:

https://sourceforge.net/tracker/index.php?func=detail&aid=1332550&group_id=30550&atid=399601

I have compared SnoopyPro output from a working device with output from
these new devices and they are quite different. (SnoopPro .usblog files
available on request.)

The latest version of the ActiveSync software contains a file
WceRndis.inf with the following comment. It makes me 100% sure that Windows
Mobile 2005 devices uses some variant of the RNDIS over USB protocol:


; WceRndis.INF -- This is the inf installation script for the stand-alone
;                  release of RNDIS-over-USB host driver for Windows Mobile USB
Function devices.

.
.
.

[WindowsCeDevices]
%WindowsCeDevice%    = RNDIS, USB\Class_EF&SubClass_01&Prot_01


The above is a modified version of the following mail I sent to the
linux-usb-devel list and Ganesh Varadarajan the other day:

http://marc.theaimsgroup.com/?l=linux-usb-devel&m=113079438715563


My recommendation is to start working on getting these devices working with the
host RNDIS over USB code in usbnet. 

SynCE user Peter McClure (owner of a "HTC Universal" device) has been in some
contact with David Brownell but has not been able to get his device working with
usbnet yet.

I expect that the primary reason for usbnet not working with these devices is
that usbnet expects RNDIS over USB devices to have
bDeviceClass/bDeviceSubClass/bDeviceProtocol set to 02/00/00 and not ef/01/01.
There may of course be other differences too...
Comment 2 Chris Morgan 2005-11-03 20:33:21 UTC
After the patch by V Ganesh to ipaq.c I get these messages in dmesg when I do:

synce-serial-config ttyUSB0
synce-serial-start

and 

synce-serial-config ttyUSB1
synce-serial-start

The control urb error is from the ttyUSB1 case.

ipaq 2-1.4:1.1: PocketPC PDA converter detected
usb 2-1.4: PocketPC PDA converter now attached to ttyUSB1
CSLIP: code copyright 1989 Regents of the University of California
PPP generic driver version 2.4.2
ip_tables: (C) 2000-2002 Netfilter core team
drivers/usb/serial/ipaq.c: ipaq_open - This device doesn't have the correct
endpoints

drivers/usb/serial/ipaq.c: ipaq_open - failed doing control urb, error -32




However if I do:

plug in axim
synce-serial-config ttyUSB0
synce-serial-start
unplug axim

Everything works fine.

Doing the same process, plugging in, config with ttyUSB1, serial-start and
unplugging results in this oops when the axim is unplugged:

ipaq 2-1.4:1.1: PocketPC PDA converter detected
usb 2-1.4: PocketPC PDA converter now attached to ttyUSB1

Comment 3 Luis F Balbinot 2005-11-09 10:00:18 UTC
Same with me. Loaded ipaq with vendor=0x413c product=0x4011 (Dell Axim x51v) and
it created /dev/tts/USB0 and /dev/tts/USB1. I'm using 2.6.13-gentoo-r3.

And ooops:

hades ~ # synce-serial-config /dev/tts/USB0

You can now run synce-serial-start to start a serial connection.

hades ~ # synce-serial-start

synce-serial-start is now waiting for your device to connect

I saw references to?
Comment 5 David Eriksson 2006-01-04 00:26:41 UTC
I just created the SynCE-WindowsMobile5 mailing list. If you are interested in
Windows Mobile 5 support in Linux and SynCE, join it and discuss with other WM5
device owners how to proceed in order to support these devices.

trying to connect an HP ipaq rx 1950 with windows mobile 5 -> I guess this
belongs here.

synce-serial-config ttyUSB0 , synce-serial-start

Comment 9 Greg Kroah-Hartman 2006-06-21 09:31:55 UTC
Can you please try the 2.6.17 kernel release instead of 2.6.16?
Comment 10 Peter Kreussel 2006-06-22 01:27:02 UTC
Sorry, should have tried 2.6.17 in the first place.
This is the reaction of Kernel 2.6.17.1 (plain vanilla):

Comment 11 Greg Kroah-Hartman 2006-08-30 01:14:08 UTC
I really don't know what to suggest here.

If someone can point me to a fix for this issue, I'll gladly apply it.

Are you still having this same problem on the latest 2.6.18-rc5 release?
Comment 12 Luiz Fernando N. Capitulino 2006-09-11 12:35:58 UTC
Yes, there're some fixes for ip
Comment 13 Natalie Protasevich 2007-06-11 17:54:42 UTC
Peter,
Any updates on this problem? Have you tried later kernels? It's been a lot of fixes to usb after 2.6.18.

Comment 14 Adrian Bunk 2007-09-09 12:11:55 UTC
Please reopen this bug if it's still present with kernel 2.6.22.
