Hi folks, The ehci-hcd kernel module enables support for high-speed USB devices. I've noticed the following oddity: When I plug in a high-speed USB device, the CPU temperature jumps up by about 25 degrees C. The temperature stays up even after I unplug the USB device. Rmmod'ing the ehci-hcd module brings the temperature back down. I can then re-install the ehci-hcd module, and things stay normal until the next time I plug in a high-speed USB device. Here are the configuration details: Kernel 2.4.21 (vanilla) with the acpi-20030619-2.4.21.diff patch. Sharp PC-AV18 laptop (KN266, Athlon XP-M 1800+) Tested with two different models of Epson scanner, and with two different brands of external USB disks. I've also recently tried using 'athcool', which enables the VLink auto-disconnect bit and the 'bus disconnect on STPGNT' bit (this was already set). I'd hoped it might fix the odd behavior noted above, but athcool doesn't seem to make any difference. Has anybody else seen similar symptoms?
