Created attachment 10557 [details] Kernel-Messages the patch did not fixed for me. after the patch is only new line in the Log: usb-serial ttyUSB0: Error registering port device, continuing
But did Oliver's patch prevent the oops?
Olivers patch didnt prevent the oops. the new oops is in attachment 10557 [details]
Can you please test with newest kernel, 2.6.22-rc4? Thanks.

An obvious reason for that to be NULL is here (usb-serial.c): dbg("%s - setting up %d port structures for this device", __FUNCTION__, max_endpoints); for (i = 0; i < max_endpoints; ++i) { port = kzalloc(sizeof(struct usb_serial_port), GFP_KERNEL); if (!port) goto probe_error; port->serial = serial; spin_lock_init(&port->lock); mutex_init(&port->mutex); INIT_WORK(&port->work, usb_serial_port_work); serial->port[i] = port; } /* set up the endpoint information */ for (i = 0; i < num_bulk_in; ++i) { endpoint = bulk_in_endpoint[i]; port = serial->port[i]; port->read_urb = usb_alloc_urb (0, GFP_KERNEL); How many endpoints does this device have? Regards Oliver
Alexander, can you please attach the output from "lsusb -v" for this device?

This looks like an RNDIS device. Is there a good reason the ipaq driver should bind to it?

It's not as bad as you say. For one thing, the old kerneldoc did not explain the meaning of those fields clearly. "The number of endpoints this device will have" doesn't really mean anything, especially since it is part of a _driver_ structure, not a _device_ structure -- it would make sense to talk about "this driver" but it doesn't make sense to talk about "this device". (My version of those comments could stand to be improved also.) It certainly doesn't say that the serial core will reject devices not having exactly that many endpoints. It would be easy to change the patch so that devices have to have exactly the specified number of endpoints. But what's wrong with making the value a minimum? At least it guarantees that all the endpoints the driver wants will indeed exist.
With alans patch the ipaq module does not oops. But i cannot connect the device with synce-serial (0.10.0) synce-serial-start as root and synce-trayicon as user does not connect.

You don't make sure the device will talk to the intended endpoint. The consequences are undefined. 2. The device will end up with more struct usb_serial_port than it knows itself to have and has requested. Again consequences are undefined. 3. On the additional port structures then allocated the device won't have endpoints of the other types to talk to. Regards Oliver
Created attachment 12918 [details] Check the exact number of endpoints All right, here's a version that checks for the exact number of endpoints. It should make Oliver happier. But it won't help the synce-serial problem. Oliver will have to debug that; I don't know what's involved.
I tested last patch too. dmesg says the same as Comment #19. I tested now the gnome hal integration. (auto start of multisync an connecting device). Thats works. The appliation is started. But i dont have a ppp0 device on connect and after synce-serial-start. synce-list-programs say ** (process:9330): WARNING **: No devices connected to odccm
The ipaq driver is incorrect for this device. Unload it. Then try rndis_host.
with rndis_host i have a new network iface eth4 ! i have synce svn-Version version from gentoo-overlay installed. on start odccm eth4 is up and configured as 169.254.2.2/24 I receive this message ** (odccm:6971): DEBUG: PDA network interface discovered! udi='/org/freedesktop/Hal/devices/net_80_00_60_0f_e8_00' On Mobile device is a usb rndis interface up too and configured as 169.254.2.1/??? But i cannot ping from PS to HTC and i cannot ping from HTC to PC. pls says ** (process:7101): WARNING **: No devices connected to odccm pls: Could not find configuration at path '(Default)'

Today i tested now. this patch helped me :-) http://synce.svn.sourceforge.net/svnroot/synce/trunk/patches/linux-2.6.22-rndis_host-wm5.patch it works now ! for me is the bug closed. thanks.
I guess the pointed synce patch should be pushed to the kernel main tree as it seems to be required to get "connected" with a wm5 device. It is not yet part of the official kernel tree.

The synce project seems to support only the wm5 variant (see http://synce.svn.sourceforge.net/viewvc/synce/trunk/usb-rndis-lite/rndis_host.c). Are they overlooking something?

Yes, on smaller machines you cannot allocate more than 16K in one chunk. The VM will not cope with that load easily.
Created attachment 14722 [details] usbnet patch to compute dev->maxpacket before calling bind() Is the actual driver known to work for any RNDIS device? I tried to understand why the driver would not work with my device without the wm5 patch. Here is what I think is the problem. When the rndis_host bind() function is called (by usbnet_probe()) the dev->maxpacket is not yet set (It will be set later in usbnet_probe()). As it is 0 the computed dev->rx_urb_size is also 0 and therefore the "max_transfer_size" sent to the device in the RNDIS_MSG_INIT message is also 0. I am not sure how the device will react to this but obviously this is a bogus value. So it seems dev->maxpacket needs to be set before calling the bind() function (it makes some sense as rndis_bind() is using it). This means we need to move up the call to usb_maxpacket() in the usbnet_probe()function. But the call to usb_maxpacket() is requiring dev->out to be set which in turn requires this computation to be moved above the call to usb_maxpacket() (by the way I am not sure dev->out is set correctly with the actual version of the driver in case of a bind() device) I am attaching a proposal for a patch to fix this problem (assuming I didn't overlook anything). With this patch the dev->rx_urb_size and the "max_transfer_size" are computed to 1600 with my device (qtek 9100) which seems reasonable enough. More importantly this works for me and I am able to communicate with the smartphone (without changing rndis_host.c with the wm5 patch). Any comment is welcome.
Re Comment #37 ... a much better fix would be a one-liner to have the rndis_host code make sure that dev->maxpacket is set before it uses that value. That would obviously not affect any other usbnet minidrivers. BTW, I don't see the relationship of this usbnet bug to the original usb-serial bug. If usb-serial was wrongly grabbing the device, that's one bug and should be addressed as such. WM5 interop issues are an entirely unrelated problem.
Reopen if not fixed
