Fix for device descriptor read/64, error -71

By Jesse | February 11, 2009

This article describes the necessary steps needed to fix a system that does not recognize attached USB devices.  If you check your /var/log/messages file you will see:

Feb 11 12:39:28 localhost kernel: usb 2-5: New USB device found, idVendor=0204, idProduct=6025
Feb 11 12:39:28 localhost kernel: usb 2-5: New USB device strings: Mfr=1, Product=2, SerialNumber=3

Feb 11 12:39:29 localhost kernel: usb 8-1: new full speed USB device using uhci_hcd and address 7
Feb 11 12:39:29 localhost kernel: usb 8-1: device descriptor read/64, error -71
Feb 11 12:39:29 localhost kernel: usb 8-1: device descriptor read/64, error -71
Feb 11 12:39:29 localhost kernel: usb 8-1: new full speed USB device using uhci_hcd and address 8
Feb 11 12:39:30 localhost kernel: usb 8-1: device not accepting address 8, error -71
Feb 11 12:39:30 localhost kernel: usb 8-1: new full speed USB device using uhci_hcd and address 9
Feb 11 12:39:30 localhost kernel: usb 8-1: device not accepting address 9, error -71
Feb 11 12:39:30 localhost kernel: hub 8-0:1.0: unable to enumerate USB device on port 1

To fix this problem, reboot the machine and at the boot menu edit the kernel options and add irqpoll.

After editing irqpoll to the kernel option- the problem should go away and the device should show up as a normal USB 2.0 device.

    Alternately, one user reported that disabling ACPID under services and also adding the acpi=off also solved this issue, however I have not confirmed this yet.

    Hi

    I am running in the same issue on fedora 16. Tried the irqpoll option, but it didn’t solve it.

    What Distro/kernel are you on?
