56 Troubleshooting
Windows Vista(SP2)
Symptom 1
A bus driver that manages a Network Driver Interface Specification
(NDIS) miniport is not loaded as expected. Therefore, a yellow
exclamation mark (!) appears in Device Manager next to the device
that is driven by the miniport. The driver also displays error code 38
(CM_PROB_DRIVER_FAILED_PRIOR_UNLOAD).
For example, this problem may occur on a bus driver that manages
a USB composite device that includes a network adapter.
