From mboxrd@z Thu Jan 1 00:00:00 1970 From: Simon Wu Date: Tue, 01 Feb 2005 21:22:02 +0000 Subject: hotplug/usb.agent consumes all CPU Message-Id: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-hotplug@vger.kernel.org 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 ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
