USB Device Restart/Enable/Disable

[hid1]

Hello,
latest nrcomlib used, at Program Files\nrComm Lib\Demos\USBDeviceDemo\
usbdevicedemo.exe does not eject any USB devices.  
Custom HID devices or another. Absolutely not work.
tested on > Windows Vista

I need USB HID device eject and plug. (when devicefails)

Hello

This feature is intended for eject USB disks.
Like system well know function "Safely Remove Device" in tray box.
By the way Windows does not allow to unplug HID devices in  "Safely Remove Device".

We will try to find solution.

Ok. I will try device based fail monitor to  reset usb HID device.

[hid1]

But programmatically disable or enable HID device like device manager right click, this is possible by nrhid ?

[Roman Novgorodov]

We will try to add such functionality. But I can't promise anything :-(

Ok. thanks.

Re-detect USB Device without unplugging, USB device enable/disable, Devcon.exe can do it.  I believe, nrUSB can also. But I don't know how?

For example I need restart usb transfers for my device

Code Select Expand

devcon.exe restart USB\VID_XXXX*PID_XXXX*   This is ok with devcon. (XXX.. MY VID and MY PID) by  function DiRestartDevice? or another functions in nrwin32di unit?

I've download Windows Driver KIT. devcon.exe source available. But I 'm not familiar for cpp
