I have some different USB devices, one of them sometimes have transfer problem on some particular laptop
When I try to display the USB event log, I found
Normal device: 06 88 12 89 8a 8b 25 26 90 17
The one have transfer issue: 06 88 12 89 8a 8b 25 26 90 17 86 11 90 17 86 11 90 17
I can identify all the other code meanings with "CyU3PUsbLinkState_t" and "USB event log values"
except 0x86, so, what does this code stand for? and maybe why it was generated also?
Thanks.
Solved! Go to Solution.

Based on your log, It looks like a USB warm reset has happened, To find why this happened we need more information.
For that can you please use the USBBulkSourceSink example and provide a UART log for both scenarios one with a working setup and the second not working laptop.

Thanks for the advice, I will try to do that when I can get the laptop
To be clear, does the 0x86 0x11 mean warm reset? or, only 0x11 mean warm reset?

0x11 is a warm reset, You can refer CYU3P_USB_LOG_USBSS_RESET in this file C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\fw_lib\1_3_4\fx3_sdk_1_3_4_src\fx3_sdk_1_3_4_src\sdk\firmware\include\cyu3usb.h

What I really want is: to be sure is 0x86 has nothing to do with the problem, and no valuable clue either. I know what 0x11 mean, and any other code in the image
Thanks again, you can close this quest if no more information about 0x86
I can take 0x86 as a hidden value
