There has been at least one other similar report, about a USB mass storage device that did not work properly in the boot environment but did work properly afterward. We couldn't figure out what was wrong. Please try turning on CONFIG_USB_STORAGE_DEBUG and rebuilding your boot kernel. Then the dmesg may contain something more useful. > Second: > Not ending USB device disconnect and reconnect > Tested with Kernel 2.6.16.13-4 (SuSE), it works fine > Tested with Kernel 2.6.17, Kernel 2.6.17-mm2, Kernel 2.6.17-mm3 > dmesg shows: > usb 2-1.1: new low speed USB device using ohci_hcd and address 100 > usb 2-1.1: new device found, idVendor=046a, idProduct=0023 > usb 2-1.1: new device strings: Mfr=0, Product=0, SerialNumber=0 > usb 2-1.1: configuration #1 chosen from 1 choice > input: HID 046a:0023 as /class/input/input195 > input: USB HID v1.11 Keyboard [HID 046a:0023] on usb-0000:00:02.0-1.1 > /home/testit/kernel-source/linux-2.6.17/drivers/usb/input/hid-core.c: ctrl > urb status -110 received > input: HID 046a:0023 as /class/input/input196 > input: USB HID v1.11 Device [HID 046a:0023] on usb-0000:00:02.0-1.1 > usb 2-1.1: reset low speed USB device using ohci_hcd and address 100 > usb 2-1.1: failed to restore interface 0 altsetting 0 (error=-110) > usb 2-1.1: USB disconnect, address 100 > usb 2-1.1: new low speed USB device using ohci_hcd and address 101 > ... > and on It sounds like this keyboard just isn't working right. You can get more information by setting CONFIG_USB_DEBUG. Alan Stern Using Tomcat but need to do more? Need to support web services, security?
