During the long-term loop playback test of videos stored in the USB flash drive, it was found that the Teclast CoolFlash drive (idVendor=346d, idProduct=5678) disconnects abnormally, and the serial port reports the following error messages. [ T227] xhci-hcd xhci-hcd.7.auto: Timeout while waiting for setup device command [ T227] usb 2-1: device not accepting address 2, error -62 [ T227] xhci-hcd xhci-hcd.7.auto: Timeout while waiting for setup device command [ T227] usb 2-1: device not accepting address 2, error -62 [ T7577] xhci-hcd xhci-hcd.7.auto: xHCI host not responding to stop endpoint command [ T7577] xhci-hcd xhci-hcd.7.auto: xHCI host controller not responding, assume dead [ T7577] xhci-hcd xhci-hcd.7.auto: HC died; cleaning up [ T227] xhci-hcd xhci-hcd.7.auto: Timeout while waiting for stop endpoint command [ T7578] usb 2-1: USB disconnect, device number 2 [ T227] sd 1:0:0:0: [sde] tag#0 UNKNOWN(0x2003) Result: hostbyte=0x07 driverbyte=DRIVER_OK cmd_age=27s Adding this quirk to limit max_sectors to 64 sectors to avoid issue occurring.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
