This issue is defined by a three-way race at disconnect, between
1) Class driver interrupt endpoint resheduling attempts if the ISR gave an ep
error event due to device detach (it would try 3 times)
2) Disconnect interrupt on PORTSC_CSC, which is cleared by hub thread
asynchronously
3) The ha
Synopsis Designware USB3 IP earlier than v3.00a which is configured in silicon
with DWC_USB3_SUSPEND_ON_DISCONNECT_EN=1, would need a specific quirk to prevent
xhci host controller from dying when device is disconnected.
Since DWC_USB3_SUSPEND_ON_DISCONNECT_EN is an IP configuration whose state

These patches add support for XHCI compliant Host controller found
on Fujitsu Socs, and are based on http://lwn.net/Articles/629162/
The first patch is to add Fujitsu glue layer of Synopsis DesignWare USB3 driver
and last four patch is about quirk implementation of errata in Synopsis
DesignWare USB

As Al Viro said:
we are getting well-meaning folks who try to check that return value,
again and again, getting it wrong every time. Typical idiocies:
* return some kind of error out of ->show() on overflows. Pointless
*and* wrong - only hard errors (== fail read(2) with that) should be
The seq_printf return value, because it's frequently misused,
will eventually be converted to void.
See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to
seq_has_overflowed() and make public")
While there, simplify the error handler logic by returning
immediately and remove the unnec
When a control transfer has a short data stage, the xHCI controller generates
two transfer events: a COMP_SHORT_TX event that specifies the untransferred
amount, and a COMP_SUCCESS event. But when the data stage is not short, only the
COMP_SUCCESS event occurs. Therefore, xhci-hcd must set urb->act
