Hi All ..... any confirmation or help greatly appreciated
To clarify further....
My device uses FT232RL from Future Technology Devices International
www.ftdichip.com
I purchased from
http://www.dontronics-shop.com/super4-usb-relay-module.html
My experience is very limited, the problem could be other than the libraries
,
& the manufactures (TCTEC) (www.emx.net.au) .
The support folks from TCTEC (http://www.emx.net.au/super4usbrelay.htm)
tell me that FTPI developers will update the libftd2xx.so
library,
in the 1st quarter of 2010.
Whether this is true , and would it fix the problem I don't know.
______PROBLEM____
libftd2xx.so.0.4.1X (ALL) libraries all have a major defiency.
from kernels 2.6.18 up to 2.6.32 kernels they all suffer the same problem.
The /dev/ttyUSBX disappears when you unplug the device. .... as you would
expect!
BUT
The disappearing of the device occurs when it is still plugged in.
All you need to do is run the "lrelayset" command. either listing , setting
or unsetting will do.
Although the /dev listing disappears the "lrelayset" command is still
usable/active.!
Connecting another USB device will choose the 1st port.
Now there will be 2 devices using /dev/ttyUSB0.
& the new one(device) won't work .
So I need this fixed ASAP.
again ... any confirmation or help greatly appreciated
Cheers
Roger Salisbury
