Sorry, it's a Heisenbug. As soon as I enable CONFIG_USB_DEBUG the
message doesn't show up anymore. In the roughly corresponding section
of dmesg I have only:

<6>[   23.481711] usb 4-1: gigaset_probe: Device matched (Vendor: 0x681, Product: 0x2)

<7>[   23.684784] usb usb2: bus auto-suspend

but no "duplicate filename" message anymore. The relevant region
of the bas_gigaset driver also looks fine to me, but of course it
would, as I've written it myself.

xenon:/home/ts # lsusb -t

I'll be on a three week holiday starting tomorrow so I cannot do
any additional tests until then, but afterwards I'll gladly
investigate whether the Gigaset driver does anything bad here.
