@ mhectorgato -
I have similar setup and my spider works great, but I do have a Powered USB 3 Hub.
This has been an outstanding issue for about 6 or so months. My laptop wonāt properly recognize the device. Iāve posted screen shot after screen shot and thereās no resolution. These issue is there if I use usb or a wall wart.
@ mhectorgato - I do not think we changed anything when it comes to USB. The good news is that we have a lot more time on our hand to do specif testing or to make changes that may work around issues in specific systems/setups.
On the FEZCerbuino bee the char display is still garbled
I tried putting the using Thread.Sleep(0) that i did in the last firmware but no luck
i had to use Thread.Sleep(1) which works.
Good news is that the board must be running faster with the new firmware.
this is the code that works

You guys brought up some important points about VS2010 support. We will be trying to support VS2010 as long as we can.
I am seeing something puzzling with the latest SDK.
Target Device: Cobra II
SDK: 4.2 Gadgeteer
Attached Modules: None
I created a default Gadgeteer project with the latest SDK. Around 7 out 10 times, when I try to deploy, I get a failure after the iteration count exceeds ~50. But, if I hit the reset button, while the iteration count is occurring, VS is able to attach to the debugger and deployment succeeds. Hitting the reset key works 100% of the time.
I did nothing with the default generated Gadgeteer program except change the Debug.Print() message before each deploy attempt. I did this to insure there was code that actually needed to be deployed to the device.
Has anyone seen anything like this on a Cobra II? Or any other device?
Understood - knew you had a lot your plate!
MFDeploy on the FEZ Cerbuino bee seems a little flakey.
i have 4 of them 2 went ok 2 kept giving me a device not responding message.
i eventuallyed just tried to deploy to it and it deployed fine.
Using GHI_NETMF_Configuration_Toolv003 on the cobra 2 wint flaylessly.
Will the new fangled tool work on Cerbs?
I havenāt had any problems with it.
Iāll give that a try on my non-RT tablet 
Bingo.
FYI my SystemUpdate.Load() issue appears to have been solved by 4.2.10.0. Thanks GHI!
Using the new tool I was able to update the firmware just fine!
One hurdle down and another appears.
Am able to get the device capabilities, but canāt deploy.
What about loading a simple console āhello worldā app?
What if you hit reset when loading?
What if you used WinUSB drivers?
Am using WinUSB
Reset doesnāt seem to help
Simple app (just the Cerbuino on the designer) doesnāt deploy
Console app fails to deploy as well
What if not using winusb?
Iāve read most of the messages of this post but I think Iāve missed some elements. From now it seems that GHI will only supports VS2012. Do you know if VS2012 can be installed on Vista?
Will give it a try later on today.
