Trust me, if/when I get this working, I will post it everywhere!

I'm not sure about .NET 3.5 They may get it working, but it was recently released, so there's no telling.

Did you ever figure out how to get USB support to work with WINE? I recently got Evoscan to work using WINE 1.2, and Winetricks to load dotnetfx 1, 2, and 3. My only holdup at this point is figuring out how to get wine to point to ttyUSBx . Any ideas?

I heard a rumor that there's now OBDII support around for Linux that doesn't suck. I think my sig mentions it, but it's also available in LinuxICE now [not sure if it's working in the current beta, but nghost understands it]

I appreciate the suggestion to use LinuxICE, however Evoscan is still much further advanced, its also capable of tuning and rewriting the eeprom. At this point, if I can get the USB to work, I am golden.

Closest idea I found is called making a "symoblic link" in home/.wine/dosdevices by going:

Code:

ln -s /dev/ttyUSB0 ~/.wine/dosdevices/com1

The only problem is this makes a com port, but Evoscan doesn't use com ports, it uses USB devices.

Perhaps I can add something other than /com1, but I can't find what that is yet.

i don't know how wine works, but it should wrap the usb api's in win32 to *just work* in linux. if the app is probing for a usb device, it should find it.

idk for sure though. chances are, it just may not work.

Honestly, I have been too busy to try recompiling wine to try to get USB to work, when it works in Virtualbox.

However, you may find this of interest:
http://www.winehq.org/pipermail/wine...er/028097.html

Basically, it says that if the device shows up as a tty device, it should work... I know most USB OBD2 readers are actually serial port bridge chips, so possibly making a symlink as /dev/ttyxxx (where xxx is a non-taken number) just might work. I'm in the process of rebuilding my carPC (again) so I'll try it and see what happens.

The problem is that wine doesn't look for native USB drivers, if it's not standard emulated hardware, it won't work. I'm kind of in the same boat, HPT uses both USB and serial... but it won't recognize my USB box, and up until now I hadn't thought of symlinking it to a tty port for wine. I still don't know if it will work, but I'm going to try.

Please keep me up to date on your progress. Right now the only thing standing in my way is getting USB to work. I tried the symbolic link with no success, but this is new to me so there is a good chance I didn't do it right.

Why bother with the vm? Why not just natively run windows and save yourself a lot of time/effort?

Yeah, were not talking about VMware or Virtualbox. Our goal is to get USB to work in WINE so there is no need for a windows partition or Virtual Machine.

Ah, i see. I thought he had just resorted to using windows in a vm on top of linux. If you are going to make it work in WINE, then yeah thats much better.

I guess I missed his post referring to VM. My goal is to get this working in WINE. I will let you guys know what I find.
