View Full Version : prop based usb passthrough for a makerbot

10-15-2011, 09:13 PM

I'm trying to figure out how to do a prop based usb passthrough for a makerbot. I have the prop monitoring the temp of the platform and the print head. Now I would like to look at the data going over the usb connection. So I assume that I have to act as both a usb master and slave? Has anyone done the master part on a prop?

I appreciate any help offered.

sssidney: I think it would be easier for you to tap off the serial connection after the FTDI chip (presuming that is what is used) and then use the prop to receive on both the TXD and RXD pins i.e. snooping what is happening. You could even do a passthru here. Trying to do USB with the prop is difficult at best as it takes a lot of resources. See the thread by scanlime for the USB master and slave code.
