Makerbot 5th Generation support

[peteruithoven]

We received the first logs from Makerbot 5th Generation users. It looks like the printer driver isn't started. This could have something to do with the device path. With the current stable version we start the print3d driver when we find a /dev/ttyUSB* or /dev/ttyACM* device. (We did change to a inotifyd system) Looking at logs, the sys_devices_platform_ehci-platform_usb1.tree file seems interesting, it should contain the device name. A comparison:

A first guess is that we need another usb driver for this Makerbot version.

[woutgg]

To be able to resolve this, we would need certain information about the device to start with:

• knowing the VID/PID of the printer could help in determining which driver we need (and if it's available in OpenWRT at all);
• a log of USB data traffic during a 'regular' print session could give interesting insights (e.g. is it still x3g?);
• if the protocol is not x3g anymore, that would take resolving this issue to a whole new level...

We received the following device information from a Makerbot 5th generation user:

 MakerBot Replicator:

  Vendor ID:    0x23c1
  Version:  3.08
  Serial Number:    23C100053C7059001400
  Speed:    Up to 480 Mb/sec
  Manufacturer: MakerBot Industries
  Location ID:  0x1a120000 / 4
  Current Available (mA):   500
  Current Required (mA):    2

@jeroensomers and I looked into cracking the Makerbot 5th Gen, but where unable to make anything usefull out of it. @gryphius at https://github.com/gryphius/makerbot-gen5-api created a nice little API in python to use basic features, but I believe even he is unable to get the Makerbot to print anything. As Makerbot has chosen to drift away from the open-source community and venture into a different business model it seems to be impossible to support new Makerbot models in the future.
