Hi,
I am using and lpc4337 along with LPCopen V 2.04. The project needs to connect my 4337 host to 4 USB devices through a hub. We have a Cypress hub chip connected to USB0.

I have tried the LPCopen example for host keyboard on USB1. Would like to extend this through a hub. Are there LPCopen updates, app notes, or any documentation, or 3rd party packages that would shed some light on firmware that would support connections through a hub.

Thanks

John,

I'm in need of HUB support for the LPC4337 also.

Did you ever find anything ?

I got the hub code working in my LPC54608 design,

but back porting to the LPC4337 looks ugly.

Hoping you found something ....

Kevin

I ended up writing a HUB app for the LPC4337.

wasn't as bad as i thought.

It has TT support as well. I'm using a 4 port SMSC hub.
