I'm running Generic USB client on USB stack 2.6a on a PIC32. It has worked very well. But on some boards, it appears I'm getting a lot of bus errors with no host plugged in. This seems to result in my code spending a bunch of time servicing this interrupt instead of doing real work. I eventually get a watchdog timeout. I'm not sure this is the problem, but I've caught the system in this USB bus error several times just before the WDT times out. It seems that the lack of Vbus should indicate that no host is present and any noise on the bus would be ignored. Is there perhaps something I missed in configuring the stack? THANKS!
