I have this brand-new software RAID-1 built with two WD Elements external USB drives, and I can see that Linux repeats the following message quite a bit:

...
[302148.036912] usb 1-3.1: reset high-speed USB device number 19 using ehci_hcd
[302153.052029] usb 1-3.3: reset high-speed USB device number 20 using ehci_hcd
[302186.031481] usb 1-3.3: reset high-speed USB device number 20 using ehci_hcd
[302217.050210] usb 1-3.3: reset high-speed USB device number 20 using ehci_hcd
[302281.043543] usb 1-3.3: reset high-speed USB device number 20 using ehci_hcd
[302312.090158] usb 1-3.3: reset high-speed USB device number 20 using ehci_hcd
[302351.076851] usb 1-3.1: reset high-speed USB device number 19 using ehci_hcd
...

So, what does it say? Is this normal? Is this a problem that I should try to fix?
