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.Hi Does anybody have use a usb-serial(pl2303) device on the DVEVM? And do you have the smiliar experience? Please help me! Thank you very much! Best Regards!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!
