Subject[BUG] 2.6.32 - Sddr-09 SM reader resets endlessly
Date
Hi,

Just booted in 2.6.32 and shortly after the boot finished my console was spammed with:

[ 72.221620] usb 7-4.1: reset full speed USB device using ehci_hcd and address 5

[ 74.244640] usb 7-4.1: reset full speed USB device using ehci_hcd and address 5

I noticed the leds on the devince blinking and unplugged it. The messages stopped.

Plugging it in to another port gave:

just in case it happened to be an interaction with the hub used I tried another:

with the same results.

Ideas?
