Subject: hotplug/usb.agent consumes all CPU
Date: Tue, 01 Feb 2005 21:22:02 +0000 [thread overview]
Message-ID: <dd54e0e05020113225e614de6@mail.gmail.com> (raw)
Hello,
I am using udev with hotplug on kernel 2.6.5 and 2.6.9 (Fedora2 and 3). When I
plug one single cdc_acm device (Nokia wireless cellphones/modem) into
the USB port, dozens of hotplug usb.agent processes invoked and took
away all CPU for 7 to 8 seconds. During this time, the computer
doesn't even accept keyboard input.
If I plug N Nokia phones in the USB ports at the same time, there seem
to have N times of usb.agent processes and Nx7 seconds delay.
Any way to improve it?
Thanks,
Simon
