This link (http://www.suwa-koubou.jp/micom/USBHub/usb_hub_en.html) is from my very old archive but it might be of interest as the basis for moving forward.

Just an extract from the GB002 errata 'While operating in Host mode and attached to a
low-speed device through a full-speed USB hub,
the PRE signal may not be generated correctly.
This will result in not being able to communicate
correctly with the low-speed device.
Work around
Connect low-speed devices directly to the
application and not through a USB hub.'
As suggested above use a PIC32 harmony project. Under V2.06 there is a hub/cdc/hid project on the MZ Ef starter kit.
Or as I think already suggested. Use 2 PIC24s. And connect together using uart or spi to concentrate the two interfaces together. Can be very hard debugging hubs without the correct h/w tools.

He whose name shall not be mentioned
That is the same link as posted in post #12.

Sorry - I can't see your previous post in this thread and Post#12 is by the OP according to my browser. Perhaps another of the strange things this forum software does.

Yes, post#12 is by the OP (AndersG), and yes, it does contain that same link.
i.e. the OP was already using that link...
 

I also post at: PicForum
