Bluetooth Usb Host Controller Driver Windows 10 Macbook Pro
Agnella Caamano
I have a Macbook PRO Retina early 2015. I have installed bootcamp 6 and windows 10. I have an issue with the Iris 6100 driver (currently 15.40.0.64.4240) which is installed (with error 43). The consequence is that I cannot change the screen resolution (only 2560x1600 is possible) and therefore I cannot drive external projectors or monitors which I often use. This issue was present also in windows 8.1 (but not in windows before updating to windows 10. I have tried to install the latest intel drivers for windows 10 but it did not work. Any idea on what to try? By the way, also the Bluetooth USB Host controller driver is not working. This was ok in Windows 8.1.
Thank you for your inquiry. For Microsoft Windows 10 this is the web site to download -Iris-Graphics-6100-for-5th-Generation-Intel-Core-Processors -Iris-Graphics-6100-for-5th-Generation-Intel-Core-Processors

A new feature in iOS 5 is the support for Bluetooth 4.0 Low Energy (LE) devices using the Core Bluetooth Framework. For those who do not have a Bluetooth LE capable device, it is still possible to begin development and test Core Bluetooth iOS applications using the iOS simulator with a Bluetooth LE USB adapter. This Technical Note describes how to configure an OS X system to enable iOS simulator support for Core Bluetooth iOS applications. This Technical Note also explains the need for a Bluetooth LE adapter for OS X systems, which have Bluetooth LE built-in, for simulator testing.
This Technical Note also provides important information if you are using an OS X system for testing both iOS and OS X Core Bluetooth applications. When you make the changes described in this Technical Note, you may need to restore the system in order to run OS X Bluetooth LE application tests.
iOS 5.0 provides the Core Bluetooth framework for creating iOS applications, which can detect, connect, and communicate with Bluetooth 4.0 Low Energy (LE) devices. The standard method for testing Core Bluetooth applications is on a device such as the iPhone 4S, which has Bluetooth LE support. In order to facilitate the development of Core Bluetooth iOS applications when one does not have a Bluetooth LE iOS device, the iOS 5 SDK simulator can be used to test these applications with the help of a third-party Bluetooth LE USB adapter. This Technical Note describes the process to enable and verify simulator support on an OS X system.
Note: Developer Technical Support does not support the iOS Simulators in cases where code execution is found to be different when executed on iOS devices. When code is found to run differently on the simulator, please submit a bug report using the Apple Developer Bug Report web site Apple Developer Bug Report web site.
Important: You must test your Core Bluetooth application on an iOS device with Bluetooth 4.0 built-in before submitting the application to App Review. Do not base your iOS application submission on the success of running the application only in the iOS simulator.
For Mac systems with Bluetooth 4.0 built in, it is still a requirement to have a Bluetooth LE USB adapter in order to test iOS Core Bluetooth applications. An explanation as to why an adapter is required for this case is described in the section Bluetooth LE USB adapter Required on OS X Systems with Bluetooth 4.0 built-in
Open the System Information application to verify that the system Bluetooth driver is matched to the built-in Bluetooth host controller interface (HCI). For the Hardware->Bluetooth setting, verify that the Vendor ID is "0x5AC". Refer to Figure 1 below for an example of what the System Information application window should show.
If the system Bluetooth controller is matched to the Bluetooth LE USB adapter, then the iOS simulator will not be able to use the external Bluetooth controller for Bluetooth LE services. In this case, you might see a System Information Bluetooth panel as shown in Figure 2. Here, the Bluetooth driver is matched to the Cambridge Silicon Radio (CSR) Bluetooth LE USB adapter. If this is the case, remove the Adapter and return to Step 1 - Set the NVRAM Setting
In Xcode, launch the iOS application in the iOS 5 iPhone/iPad simulator. When the iOS simulator launches, close the application and open the Settings application and select the General tab and verify that Bluetooth is ON.
Relaunch the iOS application in the simulator. The iOS Core Bluetooth application should connect and communicate with Bluetooth LE devices, as it would when run on an iOS device with Bluetooth LE support.
Note: If there is no Bluetooth LE adapter attached to the system, it will not be possible to turn Bluetooth on in the Settings application. In running CoreBluetooth code in the simulator where there is no Bluetooth 4.0 support, -[CentralManager state] will return the CBCentralManagerStatePoweredOff result. On an iOS device with no Bluetooth LE support, -[CentralManager state] will instead return CBCentralManagerStateUnsupported.
The default behavior of the OS X Bluetooth driver is such that when an external Bluetooth HCI is attached, the driver will detach from the built-in Bluetooth interface and attach to the external HCI - if the HCI is not an Apple device. This behavior benefits OS X application developers who are developing Bluetooth LE applications, in the case that they have older Mac systems, which do not have built-in Bluetooth LE support. The developer can attach the Bluetooth LE USB adapter, the system Bluetooth driver attaches to the new HCI, then when the OS X Core Bluetooth application is run, Bluetooth LE services are accessed through the adapter. The downside here is that existing Bluetooth connections via the built-in driver are lost (Bluetooth HID devices for example).
For iOS Core Bluetooth application developers, this behavior is not compatible with the iOS simulator. In order to simulate the same Bluetooth behavior as the iOS device, the iOS simulator must open a direct connection with a Bluetooth LE HCI. If the built-in driver automatically attaches to the external Bluetooth LE HCI when it is attached, the simulator will not be able to open a connection with the external HCI. To control the driver matching behavior, the built-in Bluetooth driver recognizes the bluetoothHostControllerSwitchBehavior NVRAM setting. If the setting is set to "never", when the Bluetooth LE adapter is connected, the system Bluetooth driver does not switch to supporting the external HCI.
bluetoothHostControllerSwitchBehavior="default" // when a new HCI is connected, the built-in driver only disconnects from the built in HCI and attaches to the external HCI if the new module is not an Apple module.
On Mac systems with Bluetooth 4.0 built-in, a Bluetooth LE USB adapter is still required to support Core Bluetooth functionality in the iOS 5 simulator. As explained in Understanding the OS X Bluetooth Driver Behavior the system Bluetooth driver attaches to the built-in Bluetooth HCI. This leaves no available Bluetooth HCI for the iOS 5 simulator to attach to. For this reason, the external Bluetooth LE USB adapter is required for testing Core Bluetooth applications in the iOS 5 simulator.
Note: For Mac systems with built-in Bluetooth LE support, there is a known issue under OS X 10.7.3 in the case that an external Bluetooth LS Adapter is connected. If the built-in driver attaches to an external Bluetooth HCI leaving the built-in HCI available for the iOS simulator, the simulator fails to attach to the built-in Bluetooth HCI - Radar bug:(r. 11267888)
If your system has Bluetooth LE built-in, leave the bluetoothHostControllerSwitchBehavior="never" setting in NVRAM. With the bluetoothHostControllerSwitchBehavior setting set to "never", the system Bluetooth driver will stay matched to the built-in Bluetooth HCI which supports Bluetooth LE and OS X application will use the built-in HCI for Bluetooth LE services.
If your system does not have Bluetooth LE built-in, then to test an OS X application, you want the built-in Bluetooth driver to attach to the Bluetooth LE USB adapter to support the OS X application. To achieve this behavior, you must change the bluetoothHostControllerSwitchBehavior setting to the "default" behavior. When you want the test iOS Bluetooth LE applications in the iOS simulator, you will need to set the bluetoothHostControllerSwitchBehavior to "never".
Can you please let me know how the device appears in the device manager? Does it appear like an unknown device?
Please provide a screenshot of the same.
Also, are you seeing this issue only with the kitprog device or is this issue there for any other USB device?
Best Regards
Ekta
Attached should be a screenshot of the device manager. You can seeThe Kitprog appears as it should, However, within the 'devices and printers' control panel dialog, kitprog seems to be doing something strange - it will appear, disappear then reappear in a constant loop - as if it is resetting? This is often accompanied by the kitprog mode light flickering erratically too.
Parallels ask for permission to connect to Cypress KitPRog. After selecting yes, I see USB Serial Device (COM4, but I do not see kitprog ) under Ports(COM &LPT). Interestingly I do not see USB devices (as shown above), only USB controllers.
Some background: I am a professor at SJSU and I am using the Cyscope PSoC system to introduce transfer students to PSoC in a low-cost manner, but I did not realize that many students have MACs, and I asking them to buy a PC is not very low cost. (Sorry if this is too much information.) I have looked a the parallels website but it is slow going.
