CCS/RM48L952: RM48L952

Part Number: RM48L952
Other Parts Discussed in Thread: TUSB1105, HALCOGEN, TUSB1106

Tool/software: Code Composer Studio

Hello Sir,

Do we have different codes for (USB Device) single ended and differential ended in TUSB1105 in RM48L952 controller.

If so, can you please share me the code for differential ended as early as possible.

Best Regards,

  • Hello,

    I am not sure if two different TUSB1105 modes require different MCU code.


  • Same question was re-posted to another thread. 

  • HI,

    I have example code which(From Halcogen) is working fine in HDK board, but its not working in Custom board,

    In HDK board and Custom board we have same Micro-controller (part no RM48L952) and same USB transceiver (part No TUSB1105).

    Previously I was working with USB Transceiver TUSB1106, now I changed TUSB1106 to TUSB1105 because of Single ended and differential ended issue.

     Now i'm working with TUSB1105, the following popup is coming::

    Popup message is "USB Device not recognized" and in Device Manager "Unknown USB device (Device Descriptor Request Failed)" under  Universal Serial Bus Controllers.

    The same problem I had when i'm using  TUSB1106 .

    Please find attached screenshots.

    Kindly suggest how to make it work.

    Thanking you,

  • Hello,

    Are the MCU USB host signals connected to TUSB1105 correctly?
