Re: [bluetooth-dev] usb probelm



Hi  Greg

Thank you for your help. Now my usb trial progress a lot.
rf_conn and ppp connection between two module can be created. can ping each
other. But when I run internet explorer, it can not access any of external
address, give me meesage "host connection broke". If I convert usb to uart,
all of these work well. I wonder if there are wong packet sent back with
usb, and I donot know usb bluetooth usb driver work mechanism. Have you
tried ppp and explorer when you develop usb driver. Do you have any clue
about these.

Thanks

nixiao
