Hello,

I try:

sudo minicom -b 115200 -D /dev/ttyUSB2

After waiting a little, I type:

AT#USBCFG=4

or

AT#USBCFG=0

to reset.

Each time: Unable to open /dev/ttyUSB2

I tried with USB0 ,1, 2, 3, 4
No more.

Telit module appears with sudo lsusb

Help please.
Thanks

Hi,
Sorry, the only solution I found is to reinstall fresh system.

The message appears 1 or 2 seconds only when I reboot in minicom. But after no problems.

Sorry to don’t have any other explanation.
