LinuxQuestions.org - device descriptor read/all, error -71

I encounter a problem when plugging on my usb drive. Previously this error did not exist (All my usb devices worked fine in the past, including mouse and hard disk). The error in dmesg is as follow:

Code:

usb 4-3: new high speed USB device using ehci_hcd and address 2

usb 4-3: device descriptor read/all, error -71

usb 4-3: new high speed USB device using ehci_hcd and address 3

usb 4-3: device descriptor read/64, error -71

usb 4-3: device descriptor read/64, error -71

usb 4-3: new high speed USB device using ehci_hcd and address 4

usb 4-3: device not accepting address 4, error -71

usb 4-3: new high speed USB device using ehci_hcd and address 5

usb 4-3: device descriptor read/all, error -71

If I do 'modprobe -r ehci_hcd' and 'modprobe ehci_hcd', then the usb can be found. However, more often it does not work. I can not mount or find sda* in the /dev through 'ls /dev/sda*' command.

How to solve this problem?

Thank you very much,
