I can't reproduce this issue on my Peach Pit. What hardware is this happening on? Can you attach the USB output from chrome://device-log and the output of lsusb from chrome://system?

fwiw, no repro here either, Samus, 52.0.2743.116

Samus 53.0.2785.47 here. Sorry about the misleading version :(

Ping. Multiple people complaining. Any updates from you?

I just reproduced this on Peach Pit. There are two entries for the device in chrome://device-log from first boot, one of them is removed when the system goes to sleep but the other remains. I'm investigating further. If this is a udev issue I will simply add a workaround to the enumeration code to detect duplicate entries.

Detect duplicate USB device notifications from udev.

This patch adds a check to detect when udev has sent Chrome multiple
notifications for the same device, ignoring the duplicates, as this
behavior has been observed in the wild.

I also fix DeviceReady() to not send a device added notification if a
device was disconnected while it was being enumerated. The device would
not have been added to the global device list in this case.
