USB not detected after update

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi all,

currently on a lenovo R60, after upgrading the CentOS 5.1 I cant detect the USB device any more. The initial installation doesnt have any problems at all. Cannot find solution in forums and bugs either. I am not sure if its a bug or wrongly did an update. The lsusb did not show the device.

Things I did:

(1) updated to 2.6.18-53.1.21.el5 i686
then to 2.6.18-92.1.6.el5 i686
and here are some of the settings after update


(2) Ran  lsmod
ehci_hcd               33101  0
ohci_hcd               23261  0
uhci_hcd               25421  0

(3) Ran cat /proc/interrupts
CPU0 CPU1 0: 204299 0 IO-APIC-edge timer
 1:        208          0    IO-APIC-edge  i8042

LOC:     204143     204151
ERR:          0
MIS:          0


(4) When I plug in usb disk, the /var/log/messages shows

Jul 9 12:35:01 localhost kernel: usb 5-2: new high speed USB device using ehci_hcd and address 2 Jul 9 12:35:02 localhost kernel: ehci_hcd 0000:00:1d.7: Unlink after no-IRQ? Controller is probably using the wrong IRQ. Jul 9 12:35:12 localhost kernel: usb 5-2: device not accepting address 2, error -110

(5) checked blacklist file, no usb devices like the ehci

Before going into CentOS 5.2, I need to verify what is the problem and if it will occur again.
Any help on this?
