I have tried to start minicom with a -s option, then specify
the /dev/.static/dev/ttyUSB0, but I still can't use it
to communicat with my modem.
And do you know why my device was attached at
/dev/.static/dev/ttyUSB0 but not /dev/ttyUSB0.

Thank you very much!

Hello,All
I use a usb-serial(pl2303) device on the DVEVM.
I have compiled the kernel (Kernel v2.6.10_mvl401) to support this device by adding following options:
Support for Host-side USB
USB Serial Converter support
USB Generic Serial Driver
USB Prolific 2303 Signel Port Serial Device
And when I reboot the DVEVM with the new kernel and use "dmesg" command I can see following information about this device:
......................
Initializing USB Mass Storage driver...
usbcore: registered new driver usb-storage
USB Mass Storage support registered.
drivers/usb/serial/usb-serial.c: USB Serial support registered for Generic
usbcore: registered new driver usbserial_generic
usbcore: registered new driver usbserial
drivers/usb/serial/usb-serial.c: USB Serial Driver core v2.0
drivers/usb/serial/usb-serial.c: USB Serial support registered for PL-2303
usbcore: registered new driver pl2303
drivers/usb/serial/pl2303.c: Prolific PL2303 USB to serial adaptor driver v0.12
......................................
usb 1-1: new full speed USB device using musb_hdrc and address 2
pl2303 1-1:1.0: PL-2303 converter detected
usb 1-1: PL-2303 converter now attached to ttyUSB0
.......................................
But I cann't find ttyUSB0 in /dev, and I use "find" command to find this device , the result is:
[EMAIL PROTECTED]:~# find / -name ttyUSB0
/dev/.static/dev/ttyUSB0
/sys/class/tty/ttyUSB0
/sys/bus/usb-serial/drivers/PL-2303/ttyUSB0
/sys/bus/usb-serial/devices/ttyUSB0
/sys/devices/platform/musb_hdrc/usb1/1-1/1-1:1.0/ttyUSB0
So does it mean this device has been attached to /dev/.static/dev/ttyUSB0?
But I can't use it to communicat to the modem by minicom in using /dev/.static/dev/ttyUSB0? Why?
Thanks for any comments!
Best Regards!

I had a similiar issue under RedHat Linux. To use /dev/ttyUSB0 as an
input to minicom under RedHat Linux, I had to start minicom with a -s
option, then specify /dev/ttyUSB0. If I started up minicom using the
default selection, /dev/ttyS0, and changed to /dev/ttyUSB0, the
connection didn't work.
For what it's worth.
