Hi All, Actually I just plan to try feature of support SS hub which just enabled this
yesterday on LS1021ATWR (I know need to enable DM_USB for 1021 first).
Should the DM_USB enablement be this patch done by Alison? https://patchwork.ozlabs.org/patch/785387/
Per your knowledge, if I revert the patches I pasted in lastmail, the SS hub
support feature will be impacted or not?
Thanks.Note the SS hub support only exists in DM USB. If you revert the dwc3-xhci patchset which converts dwc3 to DM USB, you will not get the SS
hub support.
Thanks for your information, I will re-check this impact with my board. Actually I have encountered enumeration random fail issue with an USB 3.0 thumb drive (Kingston DataTraveler 3.0) after SS hub Please see attached
snapshot for details. Fail rate is about 9/30. Not sure it's relevant to SS hub patch or not yet.
Can you enable the -DDEBUG and send me the log? From the last attachment, the enumeration process already failed when getting device descriptor. Any subsequent op leads to the final BUG/reset.
I don't know where to add -DDEBUG in U-Boot Makefile, could you show me?
Anyway I've added DEBUG in file include/common.h and got some verbose log for you (seems not much in error point), pls see attached. Any further suggestion are welcome.
Regards, Bin
