usbhub-info in win32 (xp,vista ... not tested in 2000 and server 2003 , but should work)

Hi bingo,

thanks for the link,

your code look like simple ,

but whow!!

I found the following line for ctl_code:

Code: Select all

IOCTL_USB_HCD_DISABLE_PORT=CTL_CODE(#FILE_DEVICE_USB, #HCD_DISABLE_PORT, #METHOD_BUFFERED, #FILE_ANY_ACCESS)

but not found the value of the constant #HCD_DISABLE_PORT

any Idea?
thanks
jpd

or ..

Code: Select all

#USB_IOCTL_INDEX=255
#HCD_DISABLE_PORT=USB_IOCTL_INDEX+13

but me knowledge is not really properly for DDK .

Thanks
