#Usb secure 1.7 serial key software
So I have now added the procedure to the README of the software we use to control the system so it won't be forgotten (it is stored in Subversion). While you were writing the reply above I have been testing the suggestions in your linked documents and they work just fine! Just open your device by the name you gave it as "/dev/mydevice".ĭo have a read of the links I posted above for more info. Now in your code you don't need to worry about any ids and such. You can use any name descriptive of the device on the end of your serial cable.
#Usb secure 1.7 serial key serial number
What this says is that when a device with the given vendor id, product id and serial number is plugged Linux will give it the device name specified by the SYMLINK. Lsusb does not display any such information.Ĭode: Select all SUBSYSTEM="tty", ATTRS="A6008isP", SYMLINK+="arduino" Is there some way to know which of ttyUSB0 and ttyUSB1 is connected to a specific USB port? With the USB connections it is very important to know which is which, preferably by use the actual USB port it is connected to. How is this normally handled in Linux software configuration-wise? So depending on how they are detected by the operating system they get different port numbers. What happens is that the first detected converter cable gets /dev/USB0, the second /dev/USB1 etc If I attach USB to Serial converter cables I get on both Raspbian and Ubuntu: On Ubuntu 18.04 it looks like /dev/ttySN where N is a number On Raspbian Buster it looks like /dev/ttyN where N is a number. It looks like various Linux versions uses different names: Now when looking at converting the Windows code from using ports like COM1, COM2 etc into using /dev/ttyS1, /dev/ttyS2 etc I noticed two problems:ġ) The base name of serial ports is not consistent. The two channels have completely different use and are connected to different boxes. It uses two serial ports to handle external equipment and I was planning to use a pair of USB-RS232 converters.
I am planning a conversion from Windows to Raspbian of a software control program.
