Here's the author's code:. Pavel's class SetupDiWrap works great, it just needs a few small tweaks for Windows 7.
This is what works for me:. Note ulong for Reserved instead of an int. Changing uint cbSize to int cbSize saved me a cast later on, otherwise you can leave it as uint. You might also want to consider using the registry as I have found WMI quite slow 5 or 6 seconds. In my case I wanted to identify the COM port name of a device with a known friendly name. Using regedit i searched the registry for the friendly name in a key which also contained the COM port. Because the key I found was some sort of random ID along with 10 others I went up a few levels to find a key suitable to search within.
This will of course need to be modified depending upon how and where your device shows up in the registry but if you are trying to 'Auto Detect' the Com Port of a specific type of deivce then you should be able to make this work. Remember if you have to recursivly search lots of keys then this will slow the above solution down so try and find the right place in the registry to look. That is a different but probably better choice than trying to use the friendly name in the Device Manager.
Perhaps libusbp could be extended to allow access to the friendly name if you really want that. I use virtual ports generated by com0com. It seems such constructs are no ports, but the above code will treat it as serial port So I wonder how I can reliably distinguish between a valid, existing serial port name and such strange constructs Learn more.

Match friendlyName. This parameter can be NULL. I just wanted to come back and say I've been using the crap out of this code. Have had lots of projects working with serial devices lately.
Thanks for this, rather belatedly. This was the best x-mas present. To make this code work on 64bit-systems you need to change the type of the "Reserved"-field from uint to IntPtr 8bytes instead of 4 on 64bits. Note that it's a pointer , not the ulong itself!

Why do you set the "answer is not useful"? Mich - I suspect because this just gives you another fake port and name to relay to the unknown port. He still would have the problem of needing to auto discover the actual device port to set up that map in the first place. Sign up or log in Sign up using Google.
