DSUSB will not communicate with a laptop that has newer Intel Hardware
Posted: Mon Jul 17, 2017 11:07 am
I have tested DSUSB on three different computers. All are Intel based Cpu's and all are using Windows 7 X64 Professional operating systems. I am using DSUSBCheck to verify operational status.
On the laptop that does not work, DSUSB is recognized by the operating system when the device is plugged into a usb port. It is also listed in the Windows 7 "Devices an Printers" control panel. When DSUSBCheck is started it gives the "DSUSB adapter found!" message. When I try any of the commands in DSUSBCheck I get "Communication to DSUSB lost" or "Not Connected to DSUSB" message. No Commucation to the device is possible. On the other two computers DSUSBCheck functions normally and all buttons are functional.
The difference between this system and the other two computers is it uses a newer Intel Skylake Processor. It is the first Intel Chip, where Intel has removed the USB2 ports and EHCI device mode (for Usb support). It only has USB 3.0 ports with XHCI (Intel USB3.0 eXtensible Host Controller) device mode supported. I suspect that this is the problem, but cannot confirm it because I only have one system to test which contains the newer hardware.
Is there any more things I can test with this setup that would give a glue as to why it will not work?
The two systems that do work, one has a Intel Haswell Cpu and the other has a Intel Broadwell Cpu. Both systems have USB2 ports and EHCI Device mode in the Device Manager(under USB Serial BUS Controllers). On my Desktop system (Haswell cpu), I also have Eclipse Orchestrator running and this program also works with the DSUSB.
