Hi, I am trying to use this Keyspan USA-49W with a protocol analyzer, to send command to protocol analyzer and receive data from analyzer.
i have linux 2.4.7-10, RedHat 7.2. my kerenel identifies the USA-49 Hub. i am providing all the information, i think could be useful to diagnose my prolem., sorry for such big description :) dmesg |more output display following result usb-uhci.c: USB UHCI at I/O 0xdce0, IRQ 10 usb-uhci.c: Detected 2 ports usb.c: new USB bus registered, assigned bus number 1 hub.c: USB hub found hub.c: 2 ports detected usb-uhci.c: v1.251:USB Universal Host Controller Interface driver hub.c: USB new device connect on bus1/1, assigned device number 2 usb.c: USB device 2 (vend/prod 0x6cd/0x10a) is not claimed by any active driver. usbserial.c: USB Serial support registered for Generic usb.c: registered new driver serial usbserial.c: USB Serial Driver core v1.3 usbserial.c: USB Serial support registered for Keyspan USA18X - (without firmware) usbserial.c: USB Serial support registered for Keyspan USA19 - (without firmware) usbserial.c: USB Serial support registered for Keyspan USA19W - (without firmware) usbserial.c: USB Serial support registered for Keyspan USA28 - (without firmware) usbserial.c: USB Serial support registered for Keyspan USA28X - (without firmware) usbserial.c: USB Serial support registered for Keyspan USA49W - (without firmware) usbserial.c: USB Serial support registered for Keyspan USA18X usbserial.c: USB Serial support registered for Keyspan USA19 usbserial.c: USB Serial support registered for Keyspan USA19W usbserial.c: USB Serial support registered for Keyspan USA28 usbserial.c: USB Serial support registered for Keyspan USA28X usbserial.c: USB Serial support registered for Keyspan USA49W usbserial.c: Keyspan USA49W converter detected usbserial.c: Keyspan USA49W converter now attached to ttyUSB0 (or usb/tts/0 for devfs) usbserial.c: Keyspan USA49W converter now attached to ttyUSB1 (or usb/tts/1 for devfs) usbserial.c: Keyspan USA49W converter now attached to ttyUSB2 (or usb/tts/2 for devfs) usbserial.c: Keyspan USA49W converter now attached to ttyUSB3 (or usb/tts/3 for devfs) keyspan.c: v1.0.0:Keyspan USB to Serial Converter Driver I guess above means driver successfully identified the device and i can read and write to ports (1,2,3 &4) using /dev/ttyUSB0 , 1, 2, 3 etc ? i am setting port using termios structure 115200 (actually i want to use 920 kbps), Data Bits = 8, Stop Bit = 1, Parity = 0. now when i run my program say "usbsniffer /dev/ttyUSB0", i see my device light come up (which says it received something) also when hit keys (at keyboard), that light flickers indicating it received something. i used hyper term to debug, and found out i do not recived hit character (keyvoard) on hyper term -window. though my program works ok, with serial port and able to send and receive data successfully. now, i do not know how to set terminal for USB port? is something wrong there or ? or charcater set is not being identified by USB Hub, cause on hitting a key , makes cursur flicker on Hyper-term window too :), but no character is printed. i looked through net to understand it better, but .... any help ? thanks Abinash ------------------------------------------------------- This sf.net email is sponsored by: Jabber - The world's fastest growing real-time communications platform!
