Hi everyone

I am having some problems with an USB device supplied by our vendor. It
comes with a standard .inf & .sys file.

The first problem: even the driver can be installed properly in the
first time, it always will not work after I restart the computer (it
becomes Unknown Device inside Device Manager's Device List), I always
have to unplug and replug the device again for it to work properly.

Most likely a problem in the device firmware.

The second problem: if I use MS devcon or Walter Oney's FastInst to
install the .inf file automatically, I will always have BSOD right
away. However, if I install manually by running the Windows Install
Driver Wizard and select the .inf file, it can be installed without any
problem.

Bug in driver.
