USB3320 Device shutdown

Sudhirkumar Reddipalli

Other Parts Discussed in Thread: DM3730

Hi,

We are working on DM3730 custom board , designed with reference to BeagleXM RevC board.

We are using USB3320 and LAN9514 for USB and Ethernet interface.

Up-to 20 minutes (approximately) both  USB and Ethernet interface are working fine.

But suddenly USB3320 is disconnected (shutting down) and we are not able to see the device in software.

We monitored all signals for USB3320 device and are fine.

Please help us in resolving this issue.

Regards

    Hi Sudhirkumar,

    Could you give more details about the software release and kernel version which you are using? The console logs and dmesg logs should be useful.

    Hi Tsvetolin Shulev

    Thanks for the response.

    We are using DVSDK version 4.01.00.09 (ti-dvsdk_dm3730-evm_4_01_00_09)

    Linux Kernel Version 2.6.32

    When the USB3320 is shutdown the message appears :

    Hi SudhirKumar,

    The possible reason for the USB3320 device shutdown is described as comment in the ...linux/drivers/usb/core/hub.c file where comes from the first log message:

    [  238.301727] hub 2-0:1.0: port 2 disabled by hub (EMI?), re-enabling...

    Here is the comment:

    /* EM interference sometimes causes badly shielded USB devices to be shutdown by the hub, this hack enables them again.  Works at least with mouse driver. */

    Therefore I recommend you to check the connectors, lines and their shields.
