Hi netduino wiki. I have something to decompose in netduino plus. With erase pin for logic high(3.3V) on power-up, my laptop doesn't talk netduino plus which was erased. Device manager in laptop connected with netduino plus for but miscellaneous not usb of unknown device. My tryings are below. 1. Wired with logic high in erase pin on power-up. 2. Connected the usb cable between laptop and netduino plus. 3. Check the device manager which showed that connecting with miscellaneous of unknown device. 4. There wasn't any progress on me after above. 5. No samba connection with RS232 or USB. Thanks ahead.

Hi yiulsup, If you've erased your Netduino Plus using the gold ERASE pad, then you may need to specify the driver to install. Try to right-click on the device in Device Manager and select "install driver..." The SAM-BA drivers are in the "C:\Program Files (x86)\ATMEL Corporation\sam-ba_2.11\drv" folder. Chris

Hi yiulsup,

When you install the driver, follow these exact steps:

Right-click on device in Device Manager
Select "Install/Update Driver Software..."
Click "Browse my computer for driver software."
Click "Let me pick from a list of device drivers on my computer"
Press "Have Disk..." If that is not available, select "All Devices" first.
Browse to the SAM-BA drivers, then confirm.

If you let Windows look in the directory for drivers using the standard method, it will sometimes not find them.

If this does not work, please take screenshots of each step so we can see what's going on on your computer. We're glad to help; we just need more information to know where you're getting stuck.

Chris

I tried with above you adviced. But my labtop doesn't talk to netduino plus with device manager which showed that device driver for netduino doesn't working with Exclamation mark named netduino. I think there is something in .inf file for modifying and windows 7 with 64bit will be something in correction. Thanks Chris. Your time make me smile.

Have you tried plugging it in to a different USB port? I sometimes have a similar issue with win 7 x64 where unless i change the physical port in use the netduino driver is loaded not the SAM-BA one. Nak.
