DirectShow control problem of USB camera

Time:11-23

Recently used DirectShow control a dual USB camera lens (internal to a usbHub through another lens, external use a USB output)
Found it hard to solve a problem:
After open the lens, if a program anomaly exit, not closing the two lenses, then start the program again unable to open one of the lens (in respect of the equipment internal transfer Hub), at this time can only remove the USB, then plug in.
Don't know what you are a good way to, can need not to pull plug, you can open again?
