Hello; Just an update despite no reply here. :( The stalling error is not related to silicon but it is related to the USB stack. I ported the project to MPLAB and used their USB stack and everything is working as it should. I am reaching speeds of 256k/sec using bulk and ping-pong. I Hope you guys w...

The library specifically specify bulk transfer for mass storage but I am looking to implement bulk transfer only and not...
