Bug#473800: #473800- linux-image-2.6.24: Multiple "Reset high speed USB device using ehci_hcd"
Hi,
I am having more or less the same issue with 2.6.25, using an USB card
reader.
I always get "Reset high speed USB device using ehci_hcd" entries in my
logs, but after unplugging and re-plugging the device, they do not
appear anymore.
However, I haven't noticed any system crash wince I have acquired this
card reader.
I have tried disabling the USB auto-suspend, or changing the value of
the idle-delay (default to 2 secs), without success.
(log entries after booting, device connected)
