Linux/DRA722: Usb identification error

Hi guys,

i am having same descriptor issue on uBoot.
Here is my thread: e2e.ti.com/.../2182052
I am using a TI USB HUB and it works on Linux kernel fine, but have this descriptor issues on uBoot.
Any idea?

Is the U disk,Not every time you insert will not be connected.the USB voltage is normal.

Hi,The above is a log information that is not recognized at a time,The probability of error is not great.

Can you confirm by using self powered USB hub and check and see if this error does not occur ?

It does not occur when i using self powered USB hub, This will be able to explain the hardware problem?

Yeah could be some hardware problem too. What is the current requirement of connected device ?

There is no requirement, that is, U disk normal insert recognition operation.I would like to know why the device to reset it or can not be normal enumeration recognition, you must re-plug in order to connect.
"hub 3-0:1.0: port 1, status 0503, change 0000, 480 Mb/s",Misrecognized into super high speed devices.

OK,The following is my successful plug-in U disk print:
26124.00> [15815.764320] hub 3-0:1.0: port 1, status 0101, change 0000, 12 Mb/s
26124.13> [15815.884271] usb 3-1: new high-speed USB device number 2 using xhci-hcd
[15955.663201] hub 3-0:1.0: port 1, status 0100, change 0001, 12 Mb/s

"hub 3-0:1.0: port 1, status 0503, change 0000, 480 Mb/s",there is a wrong print,Why the status value and the normal insert is not the same?

That again points there could be hardware issue like interference etc. The status are different, since the USB device connected is detected as different device(failure case as USB High Speed, but success case as Low Speed). What is the actual device being connected ?

Is a USB2.0 interface U disk ,The success case as full speed.

Can you trying connecting any other USB device like Transcend etc ?

Here is the plug-in mobile hard drive after the print, are the same as the device will be recognized as full-speed mode for enumeration：

Are you using cutom DRA7x Board or the EVM ?

yes,I used the DRA722 project board.Is there any problem?
