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 can 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!
