Hi Kohji,
A regression issue has been reported when using the CHAIN-BIT patch. Can you
verify this additional patch on you hardware and report back?

Hi HPS,
The endpoint type is BULK, and the direction is OUT.
I checked by using a USB analyzer. When I did not set CHAIN bit in
LINK TRB, my host controller sent illegal packets sometimes.
But, ZLPs were sent.

Hi,
I think the xHCI host controller driver has a spec violation.
Could you refer to
``Table 126: Offset 0Ch – Link TRB Field Definitions''
in xHCI_Specification_for_USB.pdf(Revision 1.0)?
The following is an excerpt about the CHAIN BIT.

Hi HPS,
All link trbs which are not the end need CHAIN bit, I think.
But, this is errata in xHCI ver 0.95. So, linux has quirk for chain
bit. Could you check linux codes?

Hi Kohji,
I went through the Linux codes a bit, and I see

Hi Kohji,
Did you check using a USB analyzer what the difference is when setting
the CHAIN bit and not setting the chain bit?
I would guess that if you set the CHAIN-bit in this case, no ZLP will be
sent,
