apport information ** Tags added: apport-collected oneiric running-unity staging
** Description changed: When connecting to the ttyACM associated with a MSP430 microcontroller development kit, all terminal emulation programs tried show incorrect and garbled text output. When the device is plugged in dmesg reports: 092987] usb 2-1.2: new full speed USB device number 5 using ehci_hcd [ 2735.213655] cdc_acm 2-1.2:1.0: This device cannot do calls on its own. It is not a modem. [ 2735.213669] cdc_acm 2-1.2:1.0: No union descriptor, testing for castrated device [ 2735.213720] cdc_acm 2-1.2:1.0: ttyACM0: USB ACM device [ 2745.241996] generic-usb 0003:0451:F432.0003: usb_submit_urb(ctrl) failed [ 2745.242023] generic-usb 0003:0451:F432.0003: timeout initializing reports [ 2745.242401] generic-usb 0003:0451:F432.0003: hiddev0,hidraw0: USB HID v1.01 Device [Texas Instruments Texas Instruments MSP-FET430UIF] on usb-0000:00:1d.0-1.2/input1 Following this a new /dev/ttyACM0 device appears. When we connect to it printed text appears but is not complete. For instance using the same hardware and PuTTY we observe: rfcomm_send_internal cid 117 doesn't exist! BTstack counter 26230 rfcomm_send_internal cid 117 doesn't exist! BTstack counter 26231 Whereas the output observed CuteCom or minicom on Ubuntu is: BTacn 002BTacn 0 BTcct 04BTtacoe 5BTacun The particular development kit is TI's MSP430 microcontroller eZ430-RF2560. The bug was encountered testing code for the btstack project as can be seen on the following thread (http://groups.google.com/group/btstack- dev/browse_thread/thread/d9d2f8ca2baa04d7) My current belief is that this is because the device is being detected by cdc_acm as a generic USB ACM device. Another thread (http://e2e.ti.com/support/low_power_rf/f/156/t/53610.aspx) about a similar microcontroller suggests that the device should use a specific usb serial driver. We've verified that the module is compiled on our system and did a "modprobe ti_usb_3410_5052" but this had no effect on cdc_acm.
