usb device (not the storage volume type)
-
This is for generic usb devices (3 of same usb devices) I'm not sure if it is possible to do this scenario... With all 3 usb devices are on and loaded in the application... When device B is disconnected, the device B handle/instance is disposed. When device B comes back on (reconnected), the system detects device B (using the wndproc messaging), the handle/instance) is being established, without changing the intptr handle of the device A & C. Is this possible? Right now, when the application detects Device B is reconnected and powered up, the application re-scan all of usb devices (and filters out specific Product ID & Vendor ID), all of 3 devices gets new handle/instance.

I'd guess (a wild guess) that the handle for A and C wouldn't change if it's being used when B is disconnected/reconnected. (maybe google how multiple USB TV-tuners keep using the ones that arent dis-/re-connected)
