AS> I don't know what's causing this problem. Maybe it has been fixed in AS> 2.6.8-rc4. ok, i try use 2.6.8 after release >> second bug with ftdi usb/serial converter. you can see kernel output >> in kern1.log AS> This is a known bug. It happens sometimes when you rmmod one of the USB AS> host controller drivers while devices are plugged in and in use by usbfs. AS> To avoid this bug, either don't rmmod ohci_hcd or else stop all processes AS> using a USB device first. i do rmmod only if usb subsystem stop working. oops is infrequent - sometimes rmmod help, sometimes rmmod don't respond and i do reboot. how can i determine problem source instead do rmmod/modprobe or reboot? ------------------------------------------------------- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
