My wild guess is that it is not feeding power to the bus; some laptops do that. Some people have a powered usb hub for that purpose.

Maybe... or perhaps acpi.

This may be another clue: irq 7: nobody cared (try booting with the "irqpoll" option) Have you tried booting using irqpoll at the boot prompt? -- Ken Schneider SuSe since Version 5.2, June 1998 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hello,

I am experiencing this weird problem with my laptop's usb ports..

If I do not plug in my usb mouse before booting, it stays "dead", i.e. does not work at all, no light, anything.

If I have plugged it before booting, it works ok, but after the system is up, if I remove it and try to plug it back, it is again "dead".

And quite randomly, my usb ports refuse to recognize a usb memory stick..

You can find the dmesg output here:

I am running suse 10.3 (32-bit version) on hp tx1000 (amd 64-bit dual core processor)

If you remember, long time ago I was asking about sporadic hard locks that occurred on my laptop and now I am passing the following options to grub (from /boot/grub/menu.lst): ------------------------------- ###Don't change this comment - YaST2 identifier: Original name: linux### title openSUSE 10.3 - 2.6.22.17-0.1 - hard lock debug root (hd0,5) kernel /boot/vmlinuz-2.6.22.17-0.1-default root=/dev/disk/by-id/scsi-SATA_ST9160821AS_5MA6DMFC-part6 vga=0x317 resume=/dev/sda5 splash=silent showopts nohpet nolapic noapic apic=verbose initrd /boot/initrd-2.6.22.17-0.1-default ------------------------------ I suppose this has something to do with apic ?

I would post your /etc/fstab as maybe someone can identify an error there? Unless of course you have fixed it as this post is a week old?

I had a similar problem with my last set up but on suse 10.1 I found that I could often plug something into a usb socket and it would be recognised and would function. If I removed it and later plugged it in again it wouldn't work and there seemed to be no power on the socket. This could be cured by a reboot. As this only started happening many many months after I started using 10.1 I wondered if it was some sort of power save feature that had gone wrong or had been interfered with by an upgrade. It could also have been a board fault/compatability problem but I had no problems at all while running a knoppix cd. These were usb1 sockets. A knoppix cd may help you determine if your problem is software or hardware related. Since then I have installed 10.3 on a new pc and haven't had any problems at all. The new board is usb2 through out. John -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
