#8939: USB Mouse pauses erratically ---------------------------------+---------------------------- Reporter: jessicah | Owner: mmlr Type: bug | Status: new Priority: normal | Milestone: R1 Component: Drivers/Mouse/USB | Version: R1/Development Resolution: | Keywords: Blocked By: | Blocking: Has a Patch: 0 | Platform: All ---------------------------------+---------------------------- Comment (by jessicah): I'm still experiencing this problem, on different hardware. However, I'm not experiencing the high CPU load as in previous reports. I've also blacklisted drivers for intel_extreme & iprowifi4695 (intel_extreme display turns off and doesn't come back on, wireless just spams the heck out of syslog due to media changes). The notable parts of syslog that show up (using tail -f /var/log/syslog): {{{ KERN: usb error ehci -1: qtd (0xa545480) error: 0x00038d46 KERN: usb error control pipe 20: timeout waiting for queued request to complete KERN: usb error ehci -1: qtd (0xa336c00) error: 0x00038d46 KERN: usb error control pipe 20: timeout waiting for queued request to complete KERN: usb error ehci -1: qtd (0xa350180) error: 0x00088d46 KERN: usb error control pipe 14: timeout waiting for queued request to complete KERN: usb error hub 13: KERN: error updating port status KERN: usb error control pipe 20: timeout waiting for queued request to complete KERN: usb_hid: error waiting for report: Device stalled }}} The mouse then resumes normal behaviour after that until it occurs again. Which is very, very often :( It can also happen to the keyboard too, but less often (I guess less data from a keyboard?). listusb: {{{ 03f0:034a /dev/bus/usb/0/0/0 "Hewlett-Packard" "Elite Keyboard" ver. 0121 045e:00cb /dev/bus/usb/0/0/1 "Microsoft Corp."
