My driver is for usb device. I try to test
surpriseremove. HCT simulates unpluging device. My driver
steps into PnpSurpriseRemove, PnpRemove and Unload
routine. Whwn HCT try to "insert" device, the device
manager shows :"Windows cannot load the device driver for
this hardware because a previous instance of the device
driver is still in memory. (Code 38)". Why?
I've never seen this error when using this driver before.

It sounds like you have not deallocated all referenced resources. You
should run driver verifier while you are executing this test, as it
may uncover the problem for you. Otherwise you need to use your system
debugger to probe the state of all device objects, devnodes, irps,
etc. associated with your driver and device object.
