Today I attempted to configure a C927-4P using USB.
First I wanted to upgrade the Firmware from
c900-universalk9-mz.SPA.159-3.M.bin to c900-universalk9-mz.SPA.159-3.M4.bin
but when entering the USB Stick I got
"xhci_transfer_insert() should have been configured pipeh 2"
Of course I tried again with different and reformatted USB sticks.
But I kept getting the error message.
the Bugreport states the workaround of: Reload, that also did not solve the problem.
Are there any other things I can try?
