USB Device Support
Alexander: Before I go off and try to update your USB device support for the latest Wine release, are you continuing to maintain this code current to the Wine Development and Wine Stable trunks? Also, the USB Device Support in Wine Wiki page needs an update. The code at snicky.com is no longer available. Thank you for your efforts to support USB devices in Wine. James McKenzie
When last I heard from Alexander Morozov (October 2009), he wasn't working on those patches much, and had no interest in sending them to wine-patches. I did some work on USB since then, and sent some patches starting from around March 2010 (too many attempts to list, search for them). Most were rejected. The USB story goes as follows: My libusb patch was rejected IIRC because the libusb situation was unclear. There's the old libusb-0.1 and the new more powerful libusb-1.0. IIRC each *nix hacked up its own specific variation of libusb that had to be detected specifically, and some *nixes didn't support the libusb-1.0 interface yet (libusb-1.0 itself only supports Linux and MacOS when last I checked, and they were doing a Windows port). The ntoskrnl that Wine currently emulates is total bogus: one process per driver, drivers all in separate processes from each other. On Windows there's a single address space for all drivers and they can communicate amongst themselves. I don't think inter-driver communication is that crucial initially, but it will be eventually (eg. last I heard, the iPod driver stacks on top of USBSTOR.SYS, and multi-function USB devices can use a different driver for each interface - these may communicate among themselves with private ioctl requests). The big problem with the multi process situation is hardware sharing: how do you set it up so each driver accesses its own and only its own hardware? Drivers either start on system startup (Wine starts those with the first process that starts), or get loaded on-demand as the hardware is plugged in. Most drivers should install themselves to be loaded on-demand. Who loads those and how? Windows uses USBHUB.SYS to do device I/O and load drivers on demand. Alexandre didn't want that dll because it exports nothing (all its features are accessible via internal ioctls), and suggested adding the features to USBD.SYS instead, which we already have and which has exports. Now USBD.SYS is linked to by most (but not all) USB drivers so (most of the time) it automatically gets loaded into each one - great right? - but it has no idea which driver it got loaded with, nor a straightforward way to determine which device(s!) that driver wants to drive. Also, since most drivers only load on-demand, the driver will never load, and thus this won't work unless we load those drivers on startup instead. The other approach, which I tried, was to get Wine's mountmgr.sys to detect USB devices using HAL, then pass them to a loaded-on-startup instance of USBHUB.SYS using a Wine-private ioctl, which would detect the driver for the device and launch a new instance of itself that would make a device object and load the driver to attach to it. This was all a bit a hack (USBHUB.SYS uses environment variables to tell the child which device and driver to run) and Alexandre also didn't the the Wine-private ioctls. Alexander Morozov's patch did things the Windows way: all drivers in one ntoskrnl process - this won't work properly in Wine for years, if ever, since ntoskrnl is so incomplete and one bad driver will crash them all. Another possibility could be to keep drivers in separate processes, but allow inter-process communication, but I see serializing IRPs between processes as being complex and very slow. Driver installation is also quite a mission. Windows detects that the hardware doesn't have a driver installed, and then generates the device ID and compatible IDs and searches .INF files for one that can support it. Our setupapi needs to be substantially improved to be able to do the same, and some newdev.dll and manual INF parsing work to install the driver may also be necessary, and I can already think of cases where even class installers will be necessary too :-(. Wine only sends DeviceIoControl to drivers. For anything non-trivial, other file-related user-space functions (at least ReadFile, WriteFile) need to go to the driver too. The infrastructure for this does not even exist yet, and would probably affects wineserver as well. Regression tests for ntosnkrl.exe and kernel drivers don't exist, and are difficult to come up with, since we'd have to compile and load drivers on Windows and run tests that don't crash Windows :-). So the architecture for USB support is tricky to say the least. But I'd still like to resume work on my USB patches some time soon, would you like to help?

Hi I (and a lot of contributors to the Nokia forums) would like to use the Nokia PC Suite in Wine. The current status in the AppDB of Nokia PC Suite <http://appdb.winehq.org/objectManager.php?sClass=application&iId=1026> v7.x.x.x is "Garbage" because, although installation and all the other functions now (wine v1.2.2) work just fine, it is totally useless without its "Connect a Phone" function. I have written in AppDB:- by Dave <http://appdb.winehq.org/contact.php?iRecipientId=208842> on Sunday September 12th 2010, 3:34
Running Wine 1.2 (latest version on ubuntu repository), trying to install nokia pc suite 7.1.51.0. I get past the license agreement (all icons are black though, but it's not hard to guess which one is "NEXT") and choosing which directory to install to (accept the default). But then it quits and I get a window that says, ERROR_INSTALL_FAILURE. According to your website this has been tested and should install, so what's wrong?
Using latest Ubuntu-10.10 wine the installation is all visible. No connectivity, but there IS kernel support. Still investigating - will report more later... The kernel connects to my Nokia 6300 by USB as /dev/ttyACM0 I have used this with with wvdial (and other apps) to use the 6300 as an Edge modem and also with kmobile-tools to sync contacts. Surely there is a way of linking /dev/ttyACM0 into wine as a raw USB or serial port? Anyone know how? Well? -- Mike Yates Cowley Middlesex England * *

It may be "COM0:" or "com0" without the :. Then ttyACM0 is available as COM 0, but it is a classic serial port. If the app is looking for a usb to serial device with a specific USB vendor and device ID it won't find the port.

I know it is a bit off topic - but what functionality of Nokia PC Suite that you need which isn't provided by gnokii/xnokii ? I have nokia phones for nearly 10 years (actually I have never owned a different brand), and gnokii/xnokii has been sufficient for my needs all these days. Connectivity via infrared/bluetooth are okay.
