OMAPL138 USB2.0 VID/PID

Other Parts Discussed in Thread: OMAPL138

Hi,

I am developing a linux USB device drive for OMAP L138 LCDK. I can't find the VID/PID for OMAPL138. Is there VID/PID for OMAP L138? If not, can I get a free VID/PID from TI?  Any suggestions?

Thanks!

    The VID/PID is included as part of OMAPL138 driver. You need to have your own VID and PID if you are developing a product. To obtain the VID/PID, you need to contact the USB organization: www.usb.org.

    Thanks

    Hi David,

    Thank you very much for your response. I don't fully understand "The VID/PID is included as part of OMAPL138 driver." Where can I find them? I am not developing my own product right now. Honestly, I can not afford $2000 to be a usb org member. I hope to get a free VID/PID from TI  for early stage development.

    Best,

    Jian

    Jian,

    The USB VID/ PID numbers are created by the product manufacturer, not the chip manufacturer when it is ready for production. For development, the Linux gadget drivers usually have the Linux foundation VID/ PID in them initially. You do not need to substitute these with Texas Instruments USB VID/ PID numbers. The Linux Foundation vendor id is 0x1d6b and should already be in the code for the gadget USB drivers. E.g. in the folder driver/usb/gadget of the Linux kernel that you are using, check the files acm_ms.c, audio.c, webcam.c and search for "Linux Foundation" you will see the #DEFINE for that device mode. For production, your company needs to get vendor and product IDs from the USB org.
