| Subject | OT Windows USB inf files |
| Message-ID | <6f76c7cd-ec52-4675-8c8e-47bc5cb38c7d@googlegroups.com> |
Hi, There is a Forth connection in fact, as I am trying to get s USB CDC implementation to work in SwiftX on an MSP430... The MSP430 gets registered as a USB device, because the inf file that I have installed as a driver contains the correct VID and PID, plus the the necessary incantation to run the built-in Windows system file usbser.sys. But, when I try to add the serenum.sys as a service (copying that section from the inf file from a Prolific Tech USB serial port adapter) it does not get enumerated as a serial port. My questions are : 1. does anyone understand the details of how this all hangs together? 2. are there any links out there in Googleland that are not swamped by a zillion similar sounding problems? "USB" "driver" and "serial port" give a lot of help about how to install a driver for your USB cable... 3. Is there some legal recourse against the big corporations that designed USB? Something along the lines of "publishing a protocol specification with intent to cause a breach of the peace"??? Or am I speaking Hungarian? I am running Win7 64 bit, but similar problems occur on Vista 32 bit... Best regards & TIA for any clues, Howerd ( Detective at Inventio Reverse Engineering Ltd )

Particularly the Device Configuration response. Although my experience was with Windows, not Linux. > > USB is so complicated, conformance is near impossible. I am aiming for USB compatibility - enough to work. There is a whole USB certification process for companies that can afford it... I have got HID to work, and CDC part way there. One of the problems is that you cannot apply the Chuck Moore approach of limiting your code to the 0.1% of the USB spec that you actually need. You seem to neeed about 98% of the USB spec just to get Windows to register it. This is a sign of a well designed protocol - almost impossible to implement without paying USB.org large somes of money. I say "almost" impossible, because the information is out there, but it is quite well obfuscated. Best regards, Howerd

A rather low-tech but effective way is to run MODE from the commmand line, then pipe that into a text file. Then you can search the file for COMx:
MODE gives the following output:

This even works on Win7 64 bit in a cmd Window!!! So, I can see my MSP430 CDC port, COM19, but I can't see its name. This means that Windows has indeed registered it as a COM port, but Windows has decided not to let me know this fact by means of an Event. But I can't be sure that it is _my_ COM port ... Thanks for this :-) Any other ideas? Best regards, Howerd

But the problem I am having is at the Windows end... It seems like I am not the only one : https://code.google.com/p/arduino/issues/detail?id=934 Appears to be the same issue on an Arduino. I Googled Xiofen USB driver, but with no success. Is the MPE inf file proprietary? BTW the USB CDC device gets recognised as a COM port, and assigned a number (COM19). I can even write to it, but Windows is not registering it as a "COM port". The problem is that I would like to use my USBclarify program to tell me the COM port number, rather than ask the user to open Windows Device Manager and look. For this I would like to have a COMport event... Maybe there is a workaround - perhaps I could get the COMport number from the USB device filename? Best regards, Howerd
