Hi, Check using usbdump -i usbusX -f Y -s 65536 -vvv what is going on. Maybe some USB transfers are returning zero length data from the chip. --HPS -----Original message----- > From:Lev Serebryakov <lev@FreeBSD.org <mailto:lev@FreeBSD.org> > > Sent: Monday 16th September 2013 23:38 > To: Harald Schmalzbauer <h.schmalzbauer@omnilan.de <mailto:h.schmalzbauer@omnilan.de> > > Cc: FreeBSD Stable <freebsd-stable@FreeBSD.org <mailto:freebsd-stable@FreeBSD.org> >; freebsd-usb@freebsd.org <mailto:freebsd-usb@freebsd.org> > Subject: Re: umcs (4-Port-USB-serial) triggering way too much ehci IRQs > > Hello, Harald. > You wrote 16 сентября 2013 г., 20:11:38: > > HS> I have some of these 4-Port-Serial-USB-Hubs: > HS> http://www.delock.com/produkte/F_673_USB---Seriell_87414/merkmale.html <http://www.delock.com/produkte/F_673_USB---Seriell_87414/merkmale.html>; > HS> They have the MosChip MCS7840 inside, wich also understands RS485/422 > HS> besides RS232. > > HS> FreeBSDs umcs(4) supports the RS232 mode with standard baudrates and > HS> works with that device. > > HS> Unfortunately, as soon as I open any of the 4 cuaU0.x ports, there are > HS> 500irq/s from ehci. > I have only one 2-port noname adapter with this chip, which I used to > write this driver.

I fixed a number o AR9285 bugs there. Uh, I did this a few times before, and indeed it fixed some problems with wifi. Unfortunately, generally it broke more things than it fixed so I always ended up with clean re-install. Hope those bug fixes will be backported to 9-STABLE. -- Marko Cupać
