I currently have 10 USB to serial adaptors all using PL2303 chip
Ubuntu detects them OK and assigns ttyUSBx numbers at it's choice on
bootup
This machine is rarely rebooted but I need it to assign fixed tty number
per device just incase a reboot/power fail happens and also if a device
is unplugged / plugged
I understand this is to be done with udev rules....the thing is I cannot
identify between one and the other as iserial are al the same .... here
are 2 of them:
[EMAIL PROTECTED]:~# udevadm info --attribute-walk -p /class/tty/ttyUSB0 |grep
serial
SUBSYSTEMS=="usb-serial"
ATTRS{serial}=="0000:01:00.0"
[EMAIL PROTECTED]:~# udevadm info --attribute-walk -p /class/tty/ttyUSB1 |grep
serial
SUBSYSTEMS=="usb-serial"
ATTRS{serial}=="0000:01:00.0"
was this issue ever sorted or maybe there is a workaround?
