Hallo Liste! Ich habe hier einen Konverter, der über USB angeschlossen wird und eine serielle Schnittstelle bereitstellt. Leider funktioniert keinerlei Kommunikation mit einem an den Konverter angeschlossenen Modem. Hersteller des Konverters laut lsusb: Bus 005 Device 002: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter System hier: openSuSE 11.4 mit Kernel 2.6.37.6-0.5-desktop Eigentlich sollte das Ding unter Linux mit dem CH341 Modul laufen. Tut es soweit auch, wie dmesg beweist: [13769.027247] usb 5-1: new full speed USB device using uhci_hcd and address 2 [13769.179357] usb 5-1: New USB device found, idVendor=1a86, idProduct=7523 [13769.179369] usb 5-1: New USB device strings: Mfr=0, Product=2, SerialNumber=0 [13769.179377] usb 5-1: Product: USB2.0-Serial [13769.447999] usbcore: registered new interface driver usbserial [13769.449381] USB Serial support registered for generic [13769.449440] usbcore: registered new interface driver usbserial_generic [13769.449443] usbserial: USB Serial Driver core [13769.498100] USB Serial support registered for ch341-uart [13769.498154] ch341 5-1:1.0: ch341-uart converter detected [13769.511513] usb 5-1: ch341-uart converter now attached to ttyUSB0 [13769.511559] usbcore: registered new interface driver ch341 Versuche ich nun über das ttyUSB0 Device per minicom mit dem Modem zu kommunizieren, bekomme ich keinerlei Antworten vom Modem. Ich schicke also z.B. ein ATI5 an das Modem, dann blinkt sogar die Receive-Data LED am Modem kurz auf. Es erscheint aber keinerlei Antwort des Modems unter minicom. Verschiedene Schnittstellengeschwindigkeiten habe ich schon probiert, ebenso Hardware- und Software-Flowcontrol - alles ohne Erfolg. Hat von Euch jemand eine Idee, woran das liegen könnte? Wäre für jeden Tipp dankbar! Hier noch ein paar Zeilen Log, wenn ich das CH341 Modul mit der debug Option starte: Jun 29 14:05:52 notebook kernel: [14202.378444] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_open() Jun 29 14:05:52 notebook kernel: [14202.378450] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_configure() Jun 29 14:05:52 notebook kernel: [14202.378457] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_control_in(c0,5f,0000,0000,f6e6a280,8) Jun 29 14:05:52 notebook kernel: [14202.379785] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_control_out(40,a1,0000,0000) Jun 29 14:05:52 notebook kernel: [14202.380741] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_set_baudrate(9600) Jun 29 14:05:52 notebook kernel: [14202.380752] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_control_out(40,9a,1312,b202) Jun 29 14:05:52 notebook kernel: [14202.381727] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_control_out(40,9a,0f2c,000c) Jun 29 14:05:52 notebook kernel: [14202.382765] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_control_in(c0,95,2518,0000,f6e6a280,8) Jun 29 14:05:52 notebook kernel: [14202.383747] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_control_out(40,9a,2518,0050) Jun 29 14:05:52 notebook kernel: [14202.384764] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_get_status() Jun 29 14:05:52 notebook kernel: [14202.384776] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_control_in(c0,95,0706,0000,f6e6ab80,8) Jun 29 14:05:52 notebook kernel: [14202.385752] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_control_out(40,a1,501f,d90a) Jun 29 14:05:52 notebook kernel: [14202.386774] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_set_baudrate(9600) Jun 29 14:05:52 notebook kernel: [14202.386784] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_control_out(40,9a,1312,b202) Jun 29 14:05:52 notebook kernel: [14202.387721] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_control_out(40,9a,0f2c,000c) Jun 29 14:05:52 notebook kernel: [14202.388764] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_set_handshake(0x60) Jun 29 14:05:52 notebook kernel: [14202.388774] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_control_out(40,a4,ff9f,0000) Jun 29 14:05:52 notebook kernel: [14202.389754] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_get_status() Jun 29 14:05:52 notebook kernel: [14202.389766] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_control_in(c0,95,0706,0000,f6e6ab80,8) Jun 29 14:05:52 notebook kernel: [14202.390746] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_set_handshake(0x60) Jun 29 14:05:52 notebook kernel: [14202.390757] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_control_out(40,a4,ff9f,0000) Jun 29 14:05:52 notebook kernel: [14202.391769] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_set_baudrate(9600) Jun 29 14:05:52 notebook kernel: [14202.391780] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_control_out(40,9a,1312,b202) Jun 29 14:05:52 notebook kernel: [14202.392762] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_control_out(40,9a,0f2c,000c) Jun 29 14:05:52 notebook kernel: [14202.393746] /usr/src/packages/BUILD/kernel-desktop-2.6.37.6/linux-2.6.37/drivers/usb/serial/ch341.c: ch341_open -
