USBDEBUG: retry harder for slow devices

Some usb debug devices don't respond fast enough. The linux kernel
(which uses almost the same usbdebug code) added a bit more
retry code, so let's copy that. Even if it might look stupid,
i pass the DBG_LOOPS argument through all functions to keep
the code at least a bit in sync with the linux kernel code.
