Subject: [usb] USB 2.0 core K chirp generation issue?
I can confirm that this change is essential for proper operation. A few
months ago, I noticed this issue (and made the same exact change)
when the USB 2.0 function core was failing enumeration with a USB 1.1 host
when connected through a hub. I have only seen the problem with one
particular host while using a hub, and it failed about 30 percent of the
time. Prior to the change, I had never seen the core fail during enumeration
with any USB 2.0 host (with or without a hub).
I've been using this particular change (many devices, many different host
controller and hub combinations) for about 6 months and have encountered no
problems as a result of it.
