usb port problem
 
Hi everybody,

I have Debian linux server with next kernel: Linux debian-tax 2.6.24-etchnhalf.1-amd64.
Unfortunately, I get the next message: "usb 2-8: new high speed USB device using ehci_hcd and address 20" and I can't use the USB port. The pendrive and external winchester does not work.

What is the problem?

It is interesting, I used it for some monts and it was right.

I find this text in the "syslog":
"Jan 20 10:03:26 localhost kernel: usb 2-6: device descriptor read/64, error -71
Jan 20 10:03:26 localhost kernel: usb 2-6: device descriptor read/64, error -71
Jan 20 10:03:26 localhost kernel: usb 2-6: new high speed USB device using ehci_hcd and address 118
Jan 20 10:03:26 localhost kernel: usb 2-6: device not accepting address 118, error -71
Jan 20 10:03:27 localhost kernel: usb 2-6: new high speed USB device using ehci_hcd and address 119
Jan 20 10:03:27 localhost kernel: usb 2-6: device not accepting address 119, error -71
Jan 20 10:03:27 localhost kernel: usb 2-6: new high speed USB device using ehci_hcd and address 120
Jan 20 10:03:27 localhost kernel: usb 2-6: device descriptor read/64, error -71"

P.s: My English not to good.

is the one to pay attention to. Looks like the device's partition table is unreadable. Assuming you've already tried rebooting - Have you tried the disks on other computers? Does this computer have more usb ports that you can try them on?

If the disk is ok it could be the port going bad, i.e. losing power. I've gotten the same error with a WD Passport because my laptop's USB ports couldn't provide enough power so I had to use an AC powered usb hub.

It could also be a bug in the kernel. With several kernels in the 2.6.2x series I've had the same problem after swapping disks in the same usb port. A reboot would always fix that.

Hope this helps
