Hi,

I'm running Lenny, and I have no problem mounting my WD external harddrive,
and using my ASUS USB-N13 wireless NIC.

Still, when I put a couple of my flash drives into a usb slot, very little
happens.

[1183228.208121] hub 4-0:1.0: unable to enumerate USB device on port 4
[1183228.448050] usb 4-4: new high speed USB device using ehci_hcd and address
113
[1183243.540193] hub 4-0:1.0: unable to enumerate USB device on port 4
[1183243.780056] usb 4-4: new high speed USB device using ehci_hcd and address
114
[1183258.872065] hub 4-0:1.0: unable to enumerate USB device on port 4

So, unable to enumerate would be an indication of a problem then?

My other usb devices are working fine.

msoulier(a)anton:/home/msoulier$ lsmod | grep usb
usb_storage 77120 1
scsi_mod 129548 3 sd_mod,usb_storage,libata
usbcore 118224 5 rt3070sta,usb_storage,ehci_hcd,uhci_hcd

Any ideas as to what would cause this?

Thanks,
Mike

Have you discarded a bad flash unit/hardware error? I mean, does it work/
is it recognized when you plug it into another computer?

Bad cable, bad/crappy USB hub, bad device, or fried USB port. Note that if
it is not an USB port directly soldered to the motherboard, it *has* a cable
inside the chassis.

Yes. And since the rest of the devices can be enumerated, it is unlikely
that it is caused by a kernel bug, so we assume it is a hardware problem.

Do check if it is an USB 1.1 or USB 2.0 devices, and check that the other
devices that DO work are also of the same type (USB 1.1 or 2.0).

I've tried several, all of which work just fine on other linux systems and
windows systems.

I'm wondering if it has something to do with my wireless usb nic.

My NIC is working off of a port on the same cable as the one that isn't
working, and I tried one off the back of the tower which is right off of the
motherboard.

I will do some testing and get back to this thread.
