more than one USB key

[SigmaTec]

Hi all,

in order to write/read files, is this possible (by script), to mount/umount more than one USB key ? For example using an USB HUB connected at the LM, and with 2 ou 3 USB key plugged ?

Have a nice end of week.
All the best.

This should work but your hub must be externally powered, not from LM

Ok for the PU.

And for Lua script ?
Actually I use these commands :
"part = part or devn"
"os.execute('umount -f /mnt 2>&-')"
"res, stat = io.readproc('mount /dev/' .. part .. ' /mnt 2>&1')"
But how to access one USB key or another specialy on the USB Hub ?

Thank's Daniel.

Why do you need multiple drives? If you want to store large amounts of data you should use a network storage or an external database.

I chose USB keys because I have to minimize the weight of my system, which is shipped in a transportable case. The first USB key records data from the LM, the second allows a copy of the data for use on an external PC.
