USB cdce stopped working

[Matthias Apitz]

Hello,

I've just realized that while plug-in my OpenMoko Freerunner into the
USB port it does not give a cdce0 interface, but just an error:

Feb  8 16:29:26 current kernel: usb2_alloc_device:1569: set address 2
failed (USB_ERR_STALLED, ignored)

Feb  8 16:29:28 current kernel: uhub_reattach_port:416: could not

Until some days ago it worked (and I have not changed) the kernel since
then:

What could be the reason for the above message? Thx
