Hi all, I've followed the directions from the usbdux website closely and still can't make my usbdux device work... I have a USBDUX regular (not fast) plugged into a Dell Poweredge 2650 running kernel 2.6.11-8. Does anyone out there have any experience with this device that could shed some light on the situation? Here's a summary of what happen: 1) Plug in usbdux > dmesg usb 1-2: new full speed USB device using ohci_hcd and address 5 comedi: version 0.7.70 - David Schleef <ds_at_schleef.org> usbdux.c: v1.00pre11:Stirling/ITL USB-DUX -- Bernd.Porr_at_f2s.com comedi_: usbdux: setting all possible devs to invalid comedi_: usbdux_: finding a free structure for the usb-device comedi_: usbdux: usbduxsub[0] is ready to connect to comedi. comedi_: usbdux: ifnum=0 comedi_: usbdux0 has been successfully initialized. usbcore: registered new driver usbdux 2) Configure device > comedi_config /dev/comedi0 usbdux > dmesg comedi0: usbdux: usb-device 0 is attached to comedi. comedi0: successfully attached to usbdux. 3) run test program > comedilib/demo/cmd BUG in do_test_for_insn_bits() : Connection timed out command before testing: start: now 0 scan_begin: timer 1000000 convert: now 0 scan_end: count 4 stop: count 1000 first test returned 0 (success) start: now 0 scan_begin: timer 1000000 convert: now 0 scan_end: count 4 stop: count 1000 second test returned 0 (success) start time: 1116114247.607902 > dmesg usb 1-2: lt-cmd timed out on ep4out comedi0: could not transmit dux_command to the usb-device, err=-110 comedi0: usbdux_ai_cmdtest comedi0: usbdux_ai_cmdtest comedi0: usbdux_ai_cmdtest comedi0: usbdux_ai_cmdtest comedi0: usbdux_ai_cmdtest comedi0: usbdux_ai_cmd comedi 0: sending commands to the usb device: size=8 usb 1-2: lt-cmd timed out on ep4out comedi0: could not transmit dux_command to the usb-device, err=-110 4) Try other demo programs > ./insn BUG in do_test_for_insn_bits() : Connection timed out /dev/comedi0: Connection timed out > /outp -s 1 2000 BUG in do_test_for_insn_bits() : Connection timed out /dev/comedi0: Connection timed out The main problem: -110 USB ERROR Here's a sample of the output from dmesg usb 1-2: comedi_config timed out on ep0out comedi_: usbdux: result=-110 comedi_: usbdux: uppload failed comedi_: usbdux: firmware upload failed comedi0: usbdux: usb-device 0 is attached to comedi. comedi0: successfully attached to usbdux. usb 1-2: lt-insn timed out on ep4out comedi0: could not transmit dux_command to the usb-device, err=-110 usb 1-2: lt-insn timed out on ep4out comedi0: could not transmit dux_command to the usb-device, err=-110 usb 1-2: lt-outp timed out on ep4out comedi0: could not transmit dux_command to the usb-device, err=-110 usb 1-2: lt-outp timed out on ep4out comedi0: could not transmit dux_command to the usb-device, err=-110 usb 1-2: lt-cmd timed out on ep4out comedi0: could not transmit dux_command to the usb-device, err=-110 How do I resolve this -110 USB error? It appears to be caused by something in the USB part of the kernel (note that the errors all come from "usb 1-2"). Does the usbdux driver use the USB API incorrectly? Thanks for any help or guidance you can provide... Joel __________________________________ Do you Yahoo!? Yahoo! Mail - You care about security. So do we. http://promotions.yahoo.com/new_mail
