USB Bluetooth Mouse communicating on wrong endpoint #57

Closed devilicecream closed 3 years ago

devilicecream commented 8 years ago

Hi, I'm having a problem using USBProxy with a bluetooth USB mouse. Digging in the code and debugging, I found that the problem is that the Device is sending the data on the EP83, instead of sending them on the EP82, as it should do. I tested it on another machine, logging the data flow on EP82. I can't understand why, if used with USBProxy, it sends the data on EP83 instead.

Here the lsusb:

Is this lsusb output from the BBB or the target host? EP83 appears to be a valid EP, but I would expect it to be up to the firmware on the device to decide which to use.

From the interface descriptors it looks as though the dongle has separate EPs for keyboard and mouse in boot mode. EP83 appears to either be for some other type of device that may be connected to the dongle, or it may be used as a generic EP for all traffic once the host OS is up.
