Hello, some others on the list may be able to help you specifically with bulk transfers, but in general you should be able to just sumbit another buffer. You probably don't need to create another Thread, you should be able to use a single Thread to get input from that pipe. You can do syncSubmit() calls which are easy but not that fast, and once you get that working move to asyncSubmit() which is faster but more complicated.
I don't know why your device would be halting except for a bad default-control-pipe request, which it doesn't seem like you're doing? Can you give more info on what you're doing, like some example code or output? If you use java -DJAVAX_USB_MSG_LEVEL=DEBUG3 <program> it will print out a lot of JNI debugging that could help show what's wrong...
