Re: [lcd4linux] Inappropriate ioctl for device (?)

[tasos <ta...@ya...>]

Hello.This is what i have understood yesterday.
I tried to create a ttyUSB0 according to 
http://www.linux-usb.org/usb.devices.txt
but i doesn't work.the kernel doesn't recognise it as
a usb-serial device.
/dev/tts/USB0 or /dev/usb/tts/0 -> i don't have such
devices.Moreover i look at the udev rules and i saw
the directories where it creates such devices But i
don't have such devices.
Nobody is using udev?
btw suppose that i disable udev,is there any way to
know which /dev/ttyUSB*** belongs to which physical
device?I tried to use lsusb -v but i cannot get any
info from it.
So what can i do please?Does any developer watch this
mailing list?Sorry for the bothering i just have to
find a solution quickly.
I hope you can understand it.
Thanks again!
