We have problem with USB compatibility for DM8168
We are testing various USB memory sticks by exporting data.
Only one USB stick makes babble error then system reboot by HW watchdog.
This USB stick has no problem with any systems
Here is the USB stick information
Imation 8GB usb memory stick
usb 1-7.2: New USB device found, idVendor=090c, idProduct=1000
usb 1-7.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3

Please check USB compatibility with DM8168
Because of this, I tried to check eye pattern of USB port
I used USBn_TESTMODE register, but there is no signal out in test mode
Please tell me how to.
About the register, we refer to sprugx8,pdf.
