bad news im afraid, problem occurred at the first attempt on

and I'm really trying to help you analizying this code here myself,
but problem is: im far from expert on network protocol business. if it
is a network problem at all. seems to me more like a USB protocol
limit issue or something .. just FYI , limiting that first constant
to 2048 still limits my upload to 90mbps , and also still solves the
issue .. there has to be something about it obviously
On my tests I found that reduction of URE_MAX_TX from 4 to 1 actually
help a lot more without so dramatic performance decrease. Though it is
likely only a workaround and does not explain the cause, so I hope Hans
more ideas for us to test. ;)
Hi,
I've got a supposedly "broken" if_ure dongle from Alexander, but I'm
unable to reproduce the if_ure hang on two different pieces of XHCI
hardware, Intel based and AMD based, which I've got.
This leads me to believe there is a bug in the XHCI driver or hardware
on your system.
Can you share the pciconfig -lv output for your XHCI controllers?
Also, when running the stress test and you see the traffic stops, what
happens if you run this command as root on the ugen which the if_ure
belongs to:
usbconfig -d ugenX.Y dump_string 0
Does the traffic resume?
--HPS
